Silicon Nitride Ceramics

Silicon Carbide Ceramics

Product Introduction:

Silicon nitride ceramic parts are made of high-purity silicon nitride powder sintered at high temperature. They are usually used to make parts in harsh environments such as high temperature, high pressure, and corrosion, such as high-temperature turbine blades, high-pressure pump valves, and corrosion-resistant pump bodies.
