Silicon Metal Powder

Chemsize Silicon Metal Powder

Chemsize Silicon Metal Powder is a silver grey or dark grey powder with a metal luster. It has a high melting point, excellent heat resistance, high resistivity, and anti-oxidation properties. This indispensable raw material is often referred to as the "industrial monosodium glutamate" and is used in various high-tech industries.

Key Applications:

1. Used in refractories and powder metallurgy to enhance thermostability, wear resistance, and inoxidizability.


2. Basic material for organosilicon polymer synthesis in the organosilicon chemical industry.


3. Manufacture of trichlorosilane and polysilicon for hi-tech fields.


4. Metallurgy and foundry industry for alloy additives and silicon steel alloying.


5. Production of silica sol.


6. Electronics industry for various specifications based on customer needs.

Particle Size Optimization:

Chemsize Silicon Metal Powder is typically produced in a size of 0-100 mm but can be further customized to meet specific application requirements. The particle size can be controlled to enhance product performance and cost competitiveness.
