Silicon nitride has better thermal shock resistance than other ceramics. Combined with high strength, low thermal expansion, good corrosion resistance and fracture toughness, silicon nitride is often used in the aerospace or automotive industries. Other applications such as burner nozzles, molten metal processing, etc. Electrical insulation, good corrosion resistance, medium operating temperature (13000C), structural ceramics, good mechanical properties, low thermal expansion, high thermal conductivity, very good thermal shock stability, low specific gravity.
