Description

Silicon nitride ceramics have many excellent performances such as high hardness, high strength, small thermal expansion coefficient, small high temperature creep, good antioxidant performance, good thermal corrosion performance, and small friction coefficients. It is the best ceramic material in comprehensive performance. It is widely used in the fields of aerospace, high -speed rail, and new energy vehicles. It is an important core heat dissipation material for insulation grid bipolar crystal pipes (IGBT) and silicon carbide power module (SIC MOSFET).
