VOLUME-CHANGE RESISTANT SILICON OXY-NITRIDE OR SILICON OXY-NITRIDE AND SILICON NITRIDE BONDED SILICON CARBIDE REFRACTORY

摘要

A reaction sintered silicon carbide-based product, including a silicon carbide component, a bond component, wherein the bond component includes silicon oxynitride in excess of any silicon nitride of the bond component, and at least one boron component residual to an amount present prior to reaction sintering to cause increased resistance of the reaction sintered silicon carbide-based product to volume change under oxidative stress, and methods of making the same.
