ZheJiang JHC Silicon Industrial Co., Ltd. (initialed as JHC Silicon ) is a large-scaled company that
integrates the smelting of silicon metal lump, the production of silicon metal powder and the further processing of solar polysilicon. We are specialized in the research and manufacturing of further-processing products such as silicon metal powder etc. and we will gradually expand and promote the researches and sales of solar polysilicon
Industrial silicon powder:
Industrial silicon powder also known as silicon metal powder, , is one kind of silver grey or dark grey powder with metallic luster. It has features such as high melting point, good heat resistance, high resistivity, and high oxidation resistance, it is dubbed as “Industrial Glutamate ” and is an indispensable basic raw material for many high-tech industries.
(1) Silicon metal powder is widely used in fire-proof materials and powder metallurgy industries to enhance products property, such as heat resistance, abrasion resistance and anti-oxidation. Many Silicon metal powder products have been adopted in the production of steel-making furnaces, kilns, and kiln furniture.
(2) Silicon metal powder is a basic raw material in the synthesis of organic silicon macromolecule in organic silicon chemical industry. For example, it is used in the production of silicon monomer, silicone oil, and silicone rubber agent so as to improve heat resistance, electric insulation, corrosion resistance and waterproof characteristics of the products etc.
(3) Silicon metal powder can be made into polycrystalline silicon after synthesis and subsequent purification processes. Polycrystalline silicon is the basic raw material of a current green energy-solar cell.
(4) Silicon metal powder can be synthesized into polycrystalline silicon which in turn can be pulled into monocrystalline silicon. It then can be further processed into silicon chip, a critical raw material widely used in high-tech fields, such as integrated circuits and electronic components etc.
(5) In metallurgical foundry industry, silicon metal powder can be used as non-ferrous alloy additive and alloy additive of silicon and steel to enhance the hardenability of steels. Silicon metal powder can also be utilized in certain metal reducing agent and new ceramic alloys etc.
