silicon nitride powder

Silicon nitride (Si₃N₄) is a high-performance ceramic material with outstanding high-temperature resistance, high strength, high hardness, wear resistance, thermal shock resistance and excellent chemical stability. It has a low density, a small coefficient of friction and good electrical insulation. It is widely used in mechanical engineering (bearings, cutting tools), the automotive industry (turbochargers), electronics and semiconductors, aerospace and other fields, especially in extreme working conditions.
