Crack resistance of a constructional ceramic
The purpose of this article is the development and substantiation of methods of determination of crack resistance and the investigation of features of fracture of a machine building ceramic intended for use at high temperatures. Studied were a silicon nitride base reaction-sintered ceramic, designated NKKKM, and self-bonded silicon carbide produced by industry. Electrical porcelain and sodium glass were used as model materials in the development and testing of the methods.
