sealing ring

Silicon carbide or refractory gold steel grit and sand. Silicon is with quartz sand, petroleum coke (or char), production (green silicon chips to add salt) raw materials in internal resistance furnace temperature melting. At present the industrial production of green silicon carbide into black carbide and silicon carbide, two six-party crystals, weight for 3.25, microhardness 3.20 2840-3320kg/was for. this silicon ring beloings to Application of carbide sintering.have high density,Thermal conductivity is strong and Conductiviy.
