Technology of New Devitrified Ceramics a Literature Review

摘要

A comprehensive review of the worldwide open literature was made to assist the research and development engineer in future work and inform the applications engineer of the present uses and capabilities of devitrified ceramics. The devitrified ceramics of primary concern are those materials which are predominantly crystalline bodies produced by induced and controlled nucleation and crystallization of preformed glass articles. This study presents information on compositional and processing factors; fundamental phenomena; properties; the effects of crystal size, heat treatment, and composition on properties; and applications. It also includes selected abstracts. This documentary search concludes that devitrified ceramics are only in their infancy and that there is an urgent need for further development and understanding of fundamental characteristics in order to realize the full potential of these relatively new ceramic materials.
