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 for its high temperature, wear, and oxidation resistance.


2. Base material in organic silicon chemical operations for synthesizing organic silicon products like monomers, silicone oils, and rubber preservatives.


3. Utilized in the production of integrated circuits and electronics components through the manufacturing of silicon wafers.


4. Additive in metallurgical casting for nonferrous alloys and silicon steel to enhance hardness.


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


 

 

Additional Applications:

 

• Used in the production of trichlorosilane and polysilicon for hi-tech fields.


• Applied in metallurgy and foundry industry as alloy additives and alloying agents to improve hardenability.


• Utilized in the 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.
