Rare Earth Fertilizer Production The June 12, 1997 issue of China Nonferrous Metals News reported that 40 new rare earth ammonium carbonate fertilizer plants in China were recently brought on-line. The total number of facilities that are producing these fertilizers for agricultural use now number 160 [Rare Metals, 16, [3] 238 (1997)]. The 160 plants in China are producing a total of 5 million tons of rare earth ammonium carbonate fertilizer which supplies the agricultural requirements of 16.5 million acres (6.68 million hectares) of farmland.(1939-1998) Norman C. Koon, physicist at the Naval Research Laboratory, Washington, DC, died in a ski accident in January. A native of Arkansas, he earned his undergraduate and doctorate degrees in physics at Georgia Institute of Technology and then went on to spend his career at the Naval Research Laboratory where he conducted basic research. His specialty was magnetism and rare earth intermetallic compounds. He most recent work dealt with Tb-Fe layered films but he may be best remembered for his early work which ultimately led other researchers to perfect and produce the most important hard permanent magnet materials ever developed, the Nd-B-Fe alloys. Other contributions include thermal expansion measurements, magnetostriction of mixed valence and Kondo systems, spin dynamics of rare earth intermetallics, and crystal field effects in rare earth iron Laves phase compounds. 17th The Seventeenth Annual Conference on Properties and Applications of Magnetic Materials will be held May 11-13, 1998 in Chicago, Illinois, USA.

As a result of that research program, New Development of Studies on Rare Earth Complexes was published. The 944-page report contains 97 papers that review the behavior and synthesis of rare earth complex compounds.A wide selection of topics of experimentation with rare earth complexes are reported, including rare earth chemistry, synthesis, molecular and crystal structures, properties, catalytic activities of rare earth complexes and organometallics for organic reactions, RE ions in analysis, and separation processes that use RE complexes. The above topics are arranged in four sections: Fundamentals of rare earth complexes; Rare earth complexes in organic reactions, Bioreactivities of rare earth complexes and clinical analysis using rare earth complexes, and Synthesis of materials and novel separation processes via rare earth complexes. Some of the papers that will be of interest to readers contain information on electronic states and energy transfer in RE complexes, thermodynamics of rare earth ions in solution, 4f electrons in chemical bonds, oxidation of alkanes with rare earth complexes, and lanthanide triflates as water-tolerant Lewis acids. Still others will be interested in the interaction of rare earth ions with biomembranes, recognition and transformation of biomolecules with rare earth complexes, immunoassay using rare earth complexes, and the determination of genetic information using rare earth complexes. Those in industry may find the contributions on novel separation processes using RE complexes useful, such as fabrication of high strength ceramics via rare earth complexes in supercritical solvents, preparation of mesoporous activated carbon using rare earth complexes, and a new separation technique for the mutual separation and recovery of rare earths via complex formation. New Development of Studies on Rare Earth Complexes will be a valuable reference tool to researchers in academia, industry, and government institutions who are interested in the study of rare earth complex compounds. The report is was published in 1997 by the Rare Earth Society of Japan, c/o Department of Applied Chemistry, Faculty of Engineering, Osaka University, Yamadaoka 2-1, Suita, Osaka 565 Japan. The Proceedings to the International Conference on Giant Magnetostrictive Materials-Fundamentals and Application (ICGMM’96) is now available as Vol. 258 of J. Alloys and Compounds (1997). The conference was held at the Tokai University Center, Honolulu, Hawaii, USA, November 6-8, 1996. The proceedings contains 33 refereed contributions, including five invited papers which cover rare earth magnetostrictive materials, primarily terbium/dysprosium/iron alloys.Volume 258 is broken down into 4 chapters that can be classified into: fundamental aspects, material processes, devices, and thin films and design/simulation. Chapter 1 contains four papers which introduce the effects of various alloy compositions on magnetostrictive materials, low temperature oxidation of metal surfaces, hydrogen-induced anisotropy in (Dy-Tb-Fe-Co) alloys, and how vanadium alters the microstructure and magnetic properties of a Tb-Dy-Fe alloy. The next chapter will interest those contemplating manufacturing rare earth magnetostrictive materials. Two TERFENOL experts, J.D. Snodgrass and O.D. McMasters, reveal an optimized TERFENOL-D manufacturing process, while other papers report on the crystal growth of Tb-Dy-Fe alloys and the magnetic properties and thermal stability of PrFe2. The third chapter contains the most papers (15) and may be the most interesting to the neophyte as it covers how TERFENOL can be employed in actuators, transducers, motors, vibration control devices, fretting machines, torque induction, sonar systems, and others. Many diagrams of apparatus and photographs of devices and working systems are included. Several contributions provide models and simulations for testing and measuring TERFENOL performance. The last chapter deals with the latest and up-to-date discoveries of magnetostrictive thin film technology. Not only are the applications of magnetostrictive thin films explored, but magnetostrictive TbFe/Fe multilayers, and the deposition of laser-ablated and rf magnetron sputtered thin films are explained. In addition, composition effects and magnetic properties in Tb-Dy-Fe films, as well as magnetostriction in Sm-Fe-B films, are reported. Among the uses and potential applications of rare earth magnetostrictive materials, ICGMM’96 reminds us of the progress made in the study of micromachines and microelectronics and how these technologies can become advanced using rare earth magnetostrictive materials. The integration of micromachines and microelectronics form the concept of microsystem technology which is sure to be the subject of future research and interest. The success of future microsystems may rely heavily on the results of research on rare earth magnetostrictive thin films. The cost of the Proceedings to ICGMM’96 is US$///.00 and it can be ordered from Elsevier Science, P.O. Box 945, New York, NY 10159-0945; Tel: 212 633 3730; Fax: 212 633 3680; usinfo-f@elsevier.com. A four-day symposium on "High Temperature Superconductor Thin Films: Growth Mechanisms - Interfaces - Multilayers" was held during the 1996 Spring Meeting of the European Materials Society. The meeting was held in Strasbourg, France and was primarily focused on the specific topics of growth, interfaces and multilayers of High-Tc materials. As a result, the symposium covers problems associated with substrates, growth and epitaxy induced defects in these materials.The results of the meeting appear in J. Alloys and Compounds, 251, [1-2] (1997) and contains 77 papers (64 of which pertain to rare earth materials) that were presented at the European Materials Research Society 1996 Spring Meeting, Symposium F: High Temperature Conductor Thin Films: Growth Mechanisms - Interfaces - Multilayers. The 380-page volume is arranged according to ten major topics dealing with high temperature superconductors: Substrates/growth/epitaxy induced affects, Ultrathin films/grain boundary formation, Film growth/oxygen related phenomena/oxygen ordering, Structural defects and transport in HTS thin films, Tunneling barriers/heterostructures/Josephson junctions, Emerging materials/HTS thin film properties, Precursors, Deposition methods, Deposition and film characterization, and Applications. Although the majority of the rare earth-superconductor material papers deal with Yb-Ba-Cu-O (YBCO) compounds, there are other materials and topics that the attendees dealt with, such as: SrLaGaO4-SrLaAlO4 solid solutions as substrates, molecular beam epitaxy grown La2CuO4 thin films on various substrates, and the use of CeO2 in heteroepitaxial films grown by metalorganic vapor phase deposition. YBa2Cu3O7 still receives its share of attention by reports on sputtering processes for smooth surface YBCO film deposition, optical and photoacoustic studies, surface resistance and deposition temperature, and laser ablation studies. The use of organic precursors for preparing mixed-oxide superconductor materials is attracting increasing attention. Several papers deal with this technology and how it applies to chemical vapor phase deposition. The deposition kinetics of YBCO from 2,2,6,6-tertramethyl-3,5-heptanedione (thd) precursors from a single source and the various precursors used in YBCO deposition for use in a specific manufacturing environment are discussed. The researchers of High-Tc superconductors have remained focused since their experimental designs reflect the proposed end uses and ultimate application for this class of materials, which include resistive fault current limiting devices, magnetic resonance imaging, and cellular communications base stations.

Edge Technologies, the manufacturer and worldwide distributor of TERFENOL-DÒ , is adding a 20,000 square foot manufacturing facility as part of their 5-year expansion plan {The Des Moines Register, November 17, 1997, 3B (1997)}. The US$15 million expansion plan calls for a total increase of 80,000 square feet in facilities by 2002 so that the company can meet market demand for its magnetostrictive Dy-Tb-Fe alloy. The floor space of the initial facility was 10,000 square feet but additional room was needed since Edge Technologies, Inc. has experienced a 100 percent annual growth during each of the past five yearsThe initial expansion, slated to be complete this year, will triple the production capacity of the company. The additional space will be divided equally among administration, engineering, and production, since all aspects of the operation will be expanded. The company is projecting sales of its TERFENOL materials and products for 1998 to be between US$5 million and US$10 million. The powerful magnetostrictive alloy can be used in advanced flight control systems in aerospace such as those used in missiles and other vehicles where rapid reaction times are necessary. In the near-term, the company will benefit from demands of the U.S. Navy to deploy more advanced sonar systems. The new, powerful, sonar systems will utilize transducers made of TERFENOL-DÒ alloy that will eventually replace conventional piezoelectric ceramics that are currently used. The sonar related business alone could earn the company between US$20 million and US$50 million in 2002. TERFENOL-DÒ Clamps ETREMA Products, a subsidiary of Edge Technologies, is now offering wirebonding clamps made from TERFENOL-DÒ {J. Metals, 49, [12], 12 (1997)}. The clamps are suitable for sub 90 ms wire cycles that approach 20 wires/second bond capability. The clamp weighs less than 20 g but has a clamping force greater than 100 g while having an opening displacement of 140 m m. The clamp uses less than 5 watts of power and has a response time of less than 2.5 ms.

Thin Film Photonic Materials The Er3+ ion, with its intra-4f emission at 1.54; a standard telecommunications wavelength, is well suited for its application in thin film integrated optoelectronic (photonic) technology. The increased bandwidth that is available using optical communications technologies enables data information transfer at rates that are orders of magnitude higher than what is currently available in electronic materials. In the near future, Er-doped Si light emitting diodes (LEDs) could be used in Si-based optoelectronic circuits.A review by A. Polman, FOM-Institute for Atomic and Molecular Physics, Kruislaan 407, 1098 SJ Amsterdam, The Netherlands; polman@amolf.nl; http://www.amolf.nl, {J. Appl. Phys., 82, [1] 1-39 (1997)} describes the synthesis, characterization, and application of several different Er-doped thin film photonic materials. The article focuses on oxide glasses, ceramic thin films, and amorphous and crystalline silicon, all doped with Er by ion implantation. The oxide glasses that are doped with Er3+ and covered in the review include pure SiO2, phosphosilicate, borosilicate, and soda-lime glasses. In the section on silica glasses, the utility of Er3+ in pure silica is explained including the optical activation of Er, and Er3+ as a probe for irradiation damage. Other silica glasses are covered as well with upconversion and optical gain estimates and spontaneous emissions near a dielectric interface. Optical activation, upconversion, optical mode imaging, and absorption and emission cross sections are included for ceramic thin films Al2O3 and Y2O3, while Er-doped LiNbO3 contains information on not only optical activation, but also amorphization and recrystallization. A section dealing with erbium incorporation in crystalline and amorphous silicon, including solid phase crystallization and segregation, impurity effects, and ion beam induced epitaxial recrystallization will interest those involved with Er-Si materials. Optical activation in Si and codoping with explanations on photoluminescence spectra, Er ion concentration in cubic zirconia-Si, and Er ion excitation, quantum efficiency and luminescence quenching are included. Electroluminescence in both Er-doped crystalline and amorphous Si are covered as well. The author explains that Er-doping by MeV ion implantation is an ideally suited technique since the ion has the typical micron dimensions of optical materials. The role of implantation defects, effects of annealing and concentration dependence are discussed in the review and compared for the various materials. As optical technologies become more and more important in areas that have previously been the domain of electronics, the role of erbium in photonic materials will certainly increase.

In 1997, RIC published four eight-page issues of the RIC News which were sent to nearly 2,900 readers worldwide each quarter. Additional copies were sent individuals, industry, governments, and universities upon request. Of the current 2,856 RIC News subscribers, 965 are from the U.S. and 1,191 are from foreign countries, which makes the free newsletter a truly international publication. Twelve two-page issues of the monthly RIC Insight were published and sent to our 138 financial supporters (the RIC Insight is sent as a benefit to corporate supporters who contribute at least US$300.00 per year and individual supporters who contribute at least US$100.00 per year). Financial supporters are encouraged to utilize our data base services which are available to them free of charge. We also welcome donations from non-supporters in any amount to help pay publishing, printing, and mailing costs.We answered a total of 560 information requests from industry, universities, individuals, and government from 33 countries on six continents. Over two-thirds of the requests originated from industry, and nearly one-third came from foreign countries. Thirty four U.S. states were represented by the 402 domestic users. A total of 76 IS-RIC publications were distributed free of charge to people who requested them (see "Free RIC Reports" story in next column). In 1997, we added 7,866 new documents to our data base, bringing the number of documents available to be retrieved by key words and/or authors to 89,250. This represents a growth in our data base of 9.7% and is a record number of new citations that have been added to the RIC data base in one year since RIC began operation over 32 years ago! This exceeds our goal set in 1996 by 4,866 documents! By early next year, our goal is to reach 95,000 documents available to be searched by key words and/or authors. We now have 62,906 authors and 47,145 different key words in the data base to search from. The number of computer-coded references in the RIC data base should exceed 100,000 by 2000. Free and Cheap! The Rare-earth Information Center has a limited supply of IS-RIC Reports that are still available free upon request:IS-RIC-4 "Rare Earth Metals in Steels" Cheap Books In addition, we have one "steal of deal" on two overstock items: the proceedings of the Twelfth International Workshop on Rare-Earth Magnets and Their Applications and the Seventh International Symposium on Magnetic Anisotropy and Coercivity in Rare-Earth Transition Metal Alloys. These proceedings are from the conference held in Canberra, Australia, in 1992. All 1,180 pages in both the Workshop and Symposium can be yours for only US$25.00, or US$20.00 for either volume alone, including shipping. That’s less than 2.1 pennies per page of priceless research [ppppr] when you buy both volumes, delivered to your front door. At these prices, they won’t last! It’s been our experience that as conferences become a distant memory, the demand for certain papers that have been published in past proceedings increases.

EARTH DEVELOPMENT AND APPLICATIONS October 4 - October 8, 1998 Letter of Invitation Over the last few decades, the persistent efforts of the international community of scientists have led to a variety of new applications for rare earth elements, which extend beyond the traditional technological applications. These new applications are based on the unique 4f properties of the lanthanides, and have become increasingly important. The demand, for higher efficiency and more environmentally safe materials and processes, has led to a new era for rare earth materials. The new technologies, along with renovated traditional techniques, will continue to drive the rare earth markets well into the 21st century. With abundant rare earth resources, several decades of effort in China have resulted in historic progress in the rare earth industry. The application of rare earths impacts many areas of the national economy. China has become the largest producer and exporter of rare earths in the world. As a result, holding the ’98 Beijing International Exhibition on RARE EARTH DEVELOPMENT AND APPLICATIONS in China will have special significance. We are confident that in the process of realizing the goals of the Global Sustainable Development Strategy, rare earth resources and technology will contribute to the development of new advanced technologies for the future of mankind. The purpose of holding this exhibition is to show recent achievements in developing and utilizing rare earth resources worldwide, and to further promote international exchange and cooperation. We sincerely invite friends at home and abroad to this exhibition and forum, where the latest products, techniques, equipment and information will be presented. We hope that the enthusiastic participation and efforts of the worldwide rare earth community will make the exhibition and forum highly successful. Our goal is that this event will become a major forum for the world rare earth community, and will promote technical exchange and trade in the field of rare earth development and applications.
