Product Name:Silicon nitride
English Name:Silicon nitride
CAS No.:12033-89-5
Aliases:Trisilicon tetranitride
Molecular Formula:Si3N4
Physical Properties:White fluffy powder with a purity of 99.9%, average particle size of 20 nm, specific surface area of 70.625 m²/g, theoretical density of 2.501 g/cm³, bulk density of 0.102 g/cm³, melting point of 2200°C, and boiling point of 3100°C. It exhibits high UV reflectance (>95%) and infrared absorption (>97%), good chemical stability, corrosion resistance, high-temperature strength, and self-lubricating properties.
Uses:Used for manufacturing high-temperature wear-resistant structural parts in metallurgy, chemical, machinery, aerospace, and other fields; as an additive for ceramic wear-resistant composite coatings on metal surfaces and wear-resistant coatings to improve abrasion and solvent resistance; as a high-performance reinforcing phase in composite materials to enhance overall performance; also used as a release agent for quartz crucibles.
