Product Description

Industrial Silicon Metal Powder



 

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, providing 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 producing integrated circuits and electronics components using silicon wafers, driving high-tech industries forward.



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



 
5. Widely used in refractories and powder metallurgy to improve thermostability, wear resistance, and inoxidizability of products, commonly found in steel furnaces and kilns.



 
6. Basic material for organosilicon polymer synthesis, producing silicon monomers, silicone oils, and silicon rubber preservatives, improving thermostability, electric insulativity, corrosion resistance, and waterproofing of products.



 
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. Also serves as a reducing agent for certain metals and new-type ceramic alloys.



 
9. Utilized in 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.
