Glasses, ceramics, and glass‐ceramics containing carbon or nitrogen

Non‐oxide ceramics, for example SiC, Si₃N₄ and other carbides and nitrides, have been shown to have properties, particularly at elevated temperatures, which make them suitable for use under exacting environmental conditions. These materials are discussed along with partially carbon‐ and nitrogen‐substituted glasses and ceramics such as sialons (Si‐Al‐O‐N) and other oxynitride phases. The preparation and sintering characteristics as well as properties and applications are reviewed.
