Silicon Nitride :
Silicon nitride is an inorganic substance with the chemical formula Si3N4. It is an important structural ceramic material, high hardness, itself has lubricity, and wear resistance, 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, rapid cooling and then rapid heating, will not crumble.


Feature
* High thermal stability
* Strong antioxidant capacity
* Chemical stability resistance
* High temperature resistance
* Wear resistance
* High strength
* Good toughness
* Cold and heat shock resistance
* Mechanical self-lubricity




Application
* Making crucibles, etc. in the metallurgical industry
* Manufacture of high-speed turning tools, bearings, etc. in the machinery manufacturing industry
* Used as ball valves, pump bodies, sealing rings, filters, heat exchanger components and stationary catalyst carriers, combustion boats, evaporation dishes in the chemical industry;
* Used in semiconductor, aerospace, atomic energy and other industries to manufacture switching circuit substrates
