CAS 12033-89-5 Silicon Nitride

Introduction and application of CAS 12033-89-5 Silicon nitride

Silicon nitride is a chemical compound of the elements silicon and nitrogen, with the formula Si 3N 4. It is a white, high-melting-point solid that is relatively chemically inert, being attacked by dilute HF and hot H 2SO 4. It is very hard (8.5 on the mohs scale). It is the most thermodynamically stable of the silicon nitrides. Hence, Si 3N 4 is the most commercially important of the silicon nitrides and is generally understood as what is being referred to where the term "silicon nitride" is used.

As engineering ceramic material, silicon nitride powder is widely used in industry. Mainly used in ultra-high temperature gas turbine, aircraft engine, turbine blade, heat exchanger, electric furnace and so on. It can also be used as a heat-resistant coating for rockets and nuclear reactors.

Mainly used as functional ceramic materials, non-ferrous metal fusible materials, aircraft engines, gas transmission nozzles, bearings and other high-temperature structural materials and heat-resistant coating and grinding, cutting, electric furnace and other materials.
