Silicon Nitride Description Silicon nitride is an inorganic substance with chemical formula Si3N4. It is an important structural ceramic material, hardness, itself has lubricity, and wear resistance, for atomic crystal; Oxidation resistance at high temperature. And it can resist hot and cold shock, heating in the air to more than 1000 degrees Celsius, sharp cooling and sharp heating, will not shatter. Due to its excellent properties, SI3N4 is often used to manufacture fine-structured ceramic materials and advanced refractory materials with high mechanical strength.
 
Silicon Nitride Properties: Silicon nitride powder is featured by high purity, high nitrogen content, narrow granularity distribution and high sintering activity. We have developed a series of different silicon nitride products aiming at application in different fields, our products can be extensively applied in hi-tech structural ceramics, various high-abrasive materials, refractories and so on.
