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. Widely known as the "industrial monosodium glutamate," it serves as 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.


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


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


4. Added to nonferrous alloys and silicon steel in metallurgical casting to improve hardness and heat resistance.


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

Additional Uses:

• Basic material for organosilicon polymer synthesis.


• Manufacturer of trichlorosilane and polysilicon for hi-tech fields.


• Non-iron-based alloy additives and silicon steel alloying agent in metallurgy and foundry industry.


• Production of silica sol and for the electronics industry.

Specifications:

Common specifications include 40-120 mesh, 200 mesh, 325 mesh, 800 mesh, etc. Different particle size ranges are available based on customer needs.
