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 for organic silicon products synthesis, such as silicon monomers, silicone oils, and silicone rubber preservatives, providing enhanced temperature resistance, electrical insulation, corrosion resistance, and waterproofing properties.


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


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


5. Widely used in refractories and powder metallurgy to enhance thermostability, wear resistance, and inoxidizability of products.


6. Basic material for organosilicon polymer synthesis, improving product properties like thermostability, electric insulativity, corrosion resistance, and waterproofing.


7. Applied in the manufacture of trichlorosilane and polysilicon for hi-tech fields and integrated circuits.


8. Used in metallurgy and foundry industry as non-iron-based alloy additives and silicon steel alloying agent to enhance hardenability.


9. For the production of silica sol.


10. Common specifications include 40-120mesh, 200mesh, 325mesh, 800mesh, etc., with the ability to supply different particle size ranges based on customer needs.
