Oxidation in air of nitride bonded silicon carbide ceramic

Abstract : The rate of air oxidation towards 1,000degreesC of the Si3N4-bonded silicon carbide refractory is low. It is found that the porous nitride-bonding phase oxidizes mainly and that the SiC oxidation is negligible. The decrease of specific surface area, due to the growing of a dense silica layer, induces much slower kinetics.
