Sialon Ceramic Alloy

Sialon ST from McDanel Advanced Ceramic Technologies LLC is a ceramic alloy which is iso-structural with beta silicon nitride and contains aluminum and oxygen in solid solution. Consequently, it exhibits a very desirable combination of the properties of both silicon nitride (high strength, hardness, fracture toughness, and thermal shock resistance) and alumina (refractoriness, corrosion resistance, and oxidation resistance).
