Product Description

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 due to its high temperature resistance, wear resistance, and oxidation resistance.


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


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


4. As an additive in the metallurgical casting industry to enhance the hardness of nonferrous alloys and silicon steel, as well as a metal reducing agent for modern ceramic alloys.


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


6. Basic material for organosilicon polymer synthesis, producing silicon monomers, silicone oil, and silicon rubber preservatives to improve product properties.


7. Applied in the production of trichlorosilane and polysilicon for hi-tech fields and manufacturing integrated circuits and electronic components.


8. Used in metallurgy and foundry industry as non-iron-based alloy additives and silicon steel alloying agents to improve hardenability.


9. For the production of silica sol and in the electronics industry with various particle size ranges available.
