100% Beta Sialon per XRD. Sialon ST 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). It is used in thermocouple sheaths, burner tubes, and LPS tubes.Information provided by McDanel Advanced Ceramic Technologies. |
