STCERA silicon nitride ceramic part

The silicon nitride ceramics have the characteristics of high strength and high temperature resistance, which have the best comprehensive mechanical properties as well as high resistance to thermal shock, resistance to oxidation, wear resistance and resistance to corrosion among the ceramic materials; therefore, it is the first choice for the ceramic material for heat engine parts.The silicon nitride ceramics can be used as bearing ball, roller, ball race, tool and mould, new ceramic tool, pump plunger, spindle sealing material, etc. in the mechanical industry.The silicon nitride ceramics can be used as wear-resistant and corrosion-resistant parts, such as ball valve, pump body, combustion vaporizer, filter, etc., in the chemical industry.For the metallurgy purpose of the silicon nitride ceramics, due to the high temperature resistance, small friction factor, proper self-lubrication property, and stability to solution of most metals and alloys, it can be used to make the metal material processing tool and mould, such as tube pulling mandril, extrusion and ould, roller, transfer roller, heater fixture, thermocouple, metal heat treatment support, crucible, aluminum liquid conductor and aluminum-sheathed >The silicon nitride ceramics are also widely used in electronics, military and nuclear industries.
