ZhenAn Silicon Metal Powder Si 97-99.99% Manufacturer

 

       Metallic silicon powder, also known as industrial silicon powder, is silver gray or dark gray powder with metallic luster. It has a high melting point, good heat resistance, high resistivity and high antioxidant effect. Industrial 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 steel-making furnaces, kilns, and kiln furniture.

      Uses of metal silicon powder：

      1. Metallic 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 steel-making furnaces, kilns, and kiln furniture.

      2. In the silicone chemical industry, metallic silicon powder is the basic raw material for the synthesis of silicone polymers, such as used in the production of silicon monomers, silicone oil, and silicone rubber preservatives, thereby improving the high temperature resistance, electrical insulation, and corrosion resistance of the product. Anti-corrosion, waterproof and other properties.

      3. Metal silicon powder is drawn into single crystal silicon, and the processed silicon wafers are widely used in high-tech fields and are essential raw materials for integrated circuits and electronic components.

 

      Silica fume Silicon fume, also known as silica fume, is the smoke and dust recovered during the production process of metallic silicon or iron alloy. Because the silica fume contains very high silica and the particles are extremely fine, it is not only used in rubber , paint industry, and also widely used in concrete and other industries. Moreover, silica powder has pozzolanic activity.
Silica fume is generally used to control the segregation and bleeding of concrete materials, increase the compressive strength of concrete, improve the durability of concrete, and improve the impermeability, frost resistance, abrasion resistance and corrosion resistance of concrete.

      The two have different uses. The most important thing is that there is a big difference in price between silicon powder and metal silicon powder. The price of metal silicon powder is several times that of silicon powder.

Q:  What is silicon metal used for?

A：High-purity silicon metal is used by many industries. In the chemical industry it is used for producing silicon compounds as well as silicon wafers used in photovoltaic solar cells and electronic semiconductors. And aluminum manufacturers use it to improve the already useful properties of aluminum.

 

Q:  Is silicon metal rare?

A:  Silicon makes up 27.7% of the Earth's crust by mass and is the second most abundant element (oxygen is the first). It does not occur uncombined in nature but occurs chiefly as the oxide (silica) and as silicates.
