The Application of Silicon Powder

Silicon is a chemical element with the symbol Si and atomic number 14. It is from the same group with carbon, germanium and tin. They all have similar properties, and are all tetravalent metalloid and semiconductor.

Silicon powder is made from silicon lump by breaking & milling. Depending on the purity & particle size of the silicon powder, it can be used for many purposes.

Semiconductor manufacturing

Due to the high melting point, thermal stability, rich resources and higher purity of silicon powder, silicon integrated circuits and large-scale integrated circuits have been applied to various areas. Silicon powder is an important raw materials of electronics and semiconductor industry

Coating Industry

-High purity Silicon Powder with suitable grain sizes for use in preparation of pressed and bonded sputtering targets and in CVD, PVD processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, ALD, MOCVD.                                                           

-Silicon powder with narrow particle size distribution is used for thermal spaying, this makes the coating dense and uniform.

Silicone industry

Silicon powder is the basic raw material of synthetic materials. It is used in the production of silicone rubber, silicone resin, silicone oil, etc. The materials are high temperature tolerant, electrical insulation, corrosion-resistant, waterproof etc.

Refractory industry

Silicon powder is an antioxidant additive in iron groove and iron ditch of Iron smelting, mud water cannon, and containing silicon carbide mixes to raise the temperature, resistant to wear and oxidation resistance.

Metallurgical and foundry industry

Silicon powder is used as non-iron-based additives, silicon steel alloy agent to enhance the harden ability of steel. Silicon powder can also be applied to certain metal reducing agent, such as a new type of ceramic alloy.

Edgetech Industries specializes in producing high purity silicon powder with customized particle size. Our standard silicon powder particle sizes: - 325 mesh, -200mes, - 100 mesh, or any size between 20-500mesh. Nanoparticles & Submicron particles are also available on request. One of our most remarkable technologies is to provide silicon powder with a narrow particle size distribution. We will talk about the manufacturing process of silicon powder, which explain the reason we can provide narrow PSD for Si powder.
