Application:

1. Metal silicon powder is widely used in refractory materials and powder metallurgy industries to improve the high temperature resistance, wear resistance, and oxidation resistance of products. Its products are widely used in steelmaking furnaces, kilns, and kiln furniture.

2. In the organic silicon chemical industry, metal silicon powder is the basic raw material for the synthesis of organic silicon polymers, such as used in the production of silicon monomers, silicone oil, silicone, organic silicon, and silicone rubber preservatives, thereby improving the high temperature resistance, electrical insulation, corrosion resistance, waterproofing and other characteristics of products.

3. In the metallurgical casting industry, metal silicon powder is used as a non iron-based alloy additive and a silicon steel alloying agent to improve the hardenability of steel. It can also be applied as a reducing agent for certain metals, for new ceramic alloys, etc.

4. Used in silicon nitride, silicon carbide, carbon nitrogen composite ceramics, silicon titanium, silicon aluminum alloys, ceramics, electronics, military, chemical, photovoltaic industries, etc.

5. Metal ceramics, important materials for space navigation. Mixing and sintering ceramics and metals to produce metal ceramic composite materials, which are resistant to high temperatures, have high toughness, and can be cut. They not only inherit the advantages of metals and ceramics, but also make up for their inherent defects.
