SIC REFRACTORY BONDED WITH SILICON NITRIDE AND ITS PRODUCTION

摘要

PURPOSE:To obtain the subject material having improved high-temperature mechanical strength and thermal shock resistance by bonding SiC particles with a binder consisting of silicon nitride. CONSTITUTION:SiC aggregate particles are mixed with metallic Si and the mixture is formed, nitrided and repeatedly oxidized in an atmosphere having a prescribed oxygen concentration at a prescribed temperature for a prescribed period to obtain the objective SiC refractory having excellent thermal shock resistance.
