industrial applications


Silicon nitride ceramic, chemical formula Si3N4, is an important industrial ceramic material with most comprehensive performance. The properties of mechanical strength, fracture toughness, wear resistance, thermal shock resistance are ranking in first class among all industrial ceramics. The mechanical strength of silicon nitride ceramics can be maintained to a maximum working temperature of 1200 ℃. Silicon nitride ceramic will not be infiltrated or corroded by many molten metals or alloys such as aluminum, lead, tin, silver, brass, nickel, etc. The application range of silicon nitride ceramic is very wide, it can be used for wear resistant or corrosion resistant parts in both room temperature and high temperature, it can also withtand rapid temperature change of heating or cooling.
