The American Ceramic Society (ACerS), Westerville, Ohio, released Silicon Based Structural Ceramics for the New Millennium, Volume 142 in the Ceramics Transactions Series. The book focuses on recent scientific and technological developments in silicon-based (i.e., silicon nitride, SiAlONs, silicon carbide, silicon oxynitride) structural ceramics. Authors from academia and industry assess the current state of the art in silicon-based structural ceramics. Industrial case studies highlight the development and application of these materials in real engineering environments.
