English | ISBN: 1466564024 | 2014 | 371 pages | PDF | 8 MB
Recent studies indicate that China accounts for about 96 percent of theworld’s supply of rare earth materials (REMs). With REMs becoming increasinglyimportant for a growing number of high-tech applications, appropriate actionmust be taken to mitigate the effects of a shortage of critical REMs in defensesystems and components.
Bringing together information previously available only from disparate journalarticles and databases, Rare Earth Materials: Properties and Applicationsdescribes the unique characteristics and applications of 17 REMs. It definestheir chemical, electrical, thermal, and optical characteristics. Maintaining afocus on physical and chemical properties, it addresses the history andcritical issues pertaining to mining and processing of REMs.
In this book, Dr. A.R. Jha continues his distinguished track record ofdistilling complex theoretical physical concepts into an understandabletechnical framework that can be extended to practical applications acrosscommercial and industrial frameworks. He summarizes the chemical, optical,electrical, thermal, magnetic, and spectroscopic properties of REMs best suitedfor next-generation commercial and military systems or equipment. Coverageincludes extraction, recycling, refinement, visual inspection, identificationof spectroscopic parameters, quality control, element separation based onspecific application, pricing control, and environmental / geo-politicalconsiderations.
Potential applications are identified with an emphasis on scientificinstruments, nuclear resonance imaging equipment, MRI systems, magneticcouplers for uranium enrichment equipment, battery-electrodes, electric motors,electric generators, underwater sensors, and commercial and military sensors.The book describes unique applications of rare earth magnets in all-electricand hybrid electric cars and microwave components. It also considers the use ofrare earth magnets in commercial and military systems where weight and size arethe critical design requirements.
Suitable for both students and design engineers involved in the development ofhigh-technology components or systems, the book concludes by summarizing futureapplications in electro-optic systems and components, including infraredlasers, diode-pumped solid-state lasers operating at room temperatures, andother sophisticated military and commercial test equipment
