Silicon nitride ceramics possess excellent properties of high thermal stability, antioxidant capacity and good dimensional precision of products. It can be used to make combustion chamber in gas turbine, mechanical sealing ring, pipes and valves of electromagnetic pump for transmitting molten aluminium, permanent mold and the separation ring for molten steel.It can be used as the parts in projects of high temperature, senior refractory of metallurgical industry, anticorrosion parts and sealing parts in chemical industry and cutters in mechanical process industry.

Our silicon nitride powder has good properties of high purity, high nitrogen content, narrow particle size distribution, high sintering activity, stable chemical composition, decomposition resistance and oxidation resistance, especially high strength in high temperature, as well as self-lubrication. It will form dispersiod phase in the composite and greatly improve the comprehensive properties.
