Product Description
Silicon nitride is a kind of superhard material, which has lubricity, wear resistance, corrosion resistance and oxidation resistance at high temperature. It also resists cold and hot shocks and is heated to 1 in the air ℃ more than 1,000, rapid cooling and then rapid heating will not break apart, it is often used to make mechanical components such as bearings, turbine blades, mechanical seal rings, molds, etc.
silicon nitride ceramic has excellent mechanical, performance and processability, high temperature resistant ceramics, corrosion resistant ceramics, wear resistant ceramics, absolute magnetic ceramics, insulating ceramics and self-lubricating ceramics, etc. silicon nitride ceramic shaft sleeve is widely used in magnetic drive pump, chemical pump, mortar pump, mud pump, piston pump and so on.
