Product Description

Industrial Silicon Metal Powder Description

Industrial Silicon Metal Powder

Characteristics: Silicon metal powder is a silver-grey or dark-grey powder with a metallic luster. It has a high melting point, excellent heat resistance, high resistivity, and anti-oxidation properties. Often referred to as the "industrial monosodium glutamate," it is a crucial raw material for various high-tech industries.

Applications:

1. Used in the production of refractory materials and metallurgical applications due to its high temperature, wear, and oxidation resistance. Applications include furnace walls, kilns, and kiln furniture.



2. Base material in organic silicon chemical operations for synthesizing organic silicon products like silicon monomers, silicone oils, and silicone rubber preservatives, enhancing temperature resistance, electrical insulation, corrosion resistance, and waterproofness.



3. Utilized in the production of integrated circuits and electronics components using silicon wafers, driving high-tech industries.



4. Additive in metallurgical casting for nonferrous alloys and silicon steel, enhancing hardness. Also used as a metal reducing agent in modern ceramic alloys.



5. Widely used in refractories and powder metallurgy to improve thermostability, wear resistance, and inoxidizability in products like steel furnaces and kiln furniture.



6. Basic material for organosilicon polymer synthesis, producing silicon monomers, silicone oil, and silicon rubber preservatives to enhance product properties.



7. Applied in the production of trichlorosilane and polysilicon for hi-tech fields and manufacturing integrated circuits and electronic components.



8. Used in metallurgy and foundry industry as non-iron-based alloy additives and silicon steel alloying agents to improve hardenability and as a reducing agent in new-type ceramic alloys.



9. Utilized in the production of silica sol and for the electronics industry with various particle size ranges available based on customer needs.
