Description

Present-day interest in pyrochlore materials is immense. Academic and industrial researchers working with pyrochlore materials need a fundamental understanding of what pyrochlores are and their potential applications. Pyrochlore Ceramics: Properties, Processing, and Applications provides key knowledge and information needed on pyrochlore materials. With an emphasis on recent research developments, the contents review a broad spectrum of pyrochlore systems, focusing on their structures, their successful synthesis, multifaceted properties, and applications. The book brings all aspects together and presents recent research findings on pyrochlore materials. It will be the definitive text for all researchers who aim to venture into the eclectic world of pyrochlores. In addition, the book will be of interest to researchers who are already working on pyrochlore materials, providing them with novel information on the uncommon virtues of pyrochlore systems. All chapters presented in the book are at the cutting edge of research and have never been assembled in book form before. Any researcher working in related fields will gain not only a historical perspective but also a comprehensive overview of recent developments. The book will be a valuable reference resource for academic and industrial researchers working in ceramics and materials science, mechanical, electronics, and chemical engineering, as well as physical and chemical science.

About the Editor

Anirban Chowdhury

Dr. Anirban Chowdhury has mostly worked in the area of ceramics and process-structure relationships in advanced high-temperature materials. He earned his bachelor’s degree in Ceramic Technology from the University of Calcutta (College of Ceramic Technology) and M.Tech. in Materials Science from IIT Kanpur, India. He was also the recipient of the prestigious ORS Award and the Tetley & Lupton Scholarship during his PhD at the University of Leeds, UK (2005–2009). After he completed his PhD, he joined the Institute of Multidisciplinary Research for Advanced Materials (IMRAM) at Tohoku University, Japan, as a post-doctoral fellow. For a brief time, he also worked as a Research Associate with Prof. Atul H. Chokshi at IISc Bangalore (Dept. of Materials Engineering). In April 2012, he joined TATA Steel’s R&D division (Jamshedpur, India) and worked on various coating projects. This is also the place where he first started experimental work on pyrochlore systems. At present, he serves as an Associate Professor in the Department of Metallurgical and Materials Engineering at IIT Patna, which he joined in September 2013.
