EP2935154A1 - Sialon bonded silicon carbide material

These early silicon nitride-bonded silicon carbide materials typically contain free silica (Si0 2) in the refractory product which is detrimental to the high temperature strength of the silicon carbide. Accordingly, developments of the initial reaction-bonded silicon carbide have used a SiAlON bond phase and in particular β-SiAlON.
