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 for high temperature, wear, and oxidation resistance.


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


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


4. Additive for nonferrous alloys, silicon steel, and modern ceramic alloys to improve hardness and heat resistance.


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


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


7. Key component in the production of trichlorosilane, polysilicon, and monocrystalline silicon for hi-tech fields.


8. Used in metallurgy and foundry industry as alloy additives and alloying agents to enhance hardenability.


9. Essential for the production of silica sol and in the electronics industry for various applications.

Specifications:

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