  abstract: "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."--
