200 mesh metal silicon powder
200 mesh metallic silicon powder is silver gray with metallic luster. It has a high melting point, good heat resistance, high resistivity, and high antioxidant effect. It is called "industrial monosodium glutamate" and is an important basic industrial raw material with wide applications in many industries and fields.
In the silicone chemical industry, metallic silicon powder is the basic raw material for the synthesis of silicone polymers, such as trichlorosilane, which is used to produce silane coupling agents and important intermediates for other silicone products and the main raw material for polycrystalline silicon. Monomer, silicone oil, and silicone rubber preservatives to improve the product's high temperature resistance, electrical insulation, corrosion resistance, waterproofing and other properties.
In the metallurgical casting industry, metallic silicon powder is used as a non-ferrous additive and silicon steel alloy agent to improve the hardenability of steel. Metallic silicon powder can also be used as a reducing agent for certain metals and used in new ceramic alloys, etc.
The reactivity of metallic silicon powder is not only related to the composition, ratio, and particle size, but also to its microstructure. Its processing method, appearance, particle shape, and particle size distribution have a significant impact on the yield and application effect of the synthetic product. At present, the quality of ordinary metal silicon powder on the market varies from good to bad, and the production lacks scientific formulas and advanced powdering technology. Therefore, there are the following shortcomings: The metal silicon powder produced has poor activity, low product yield and low self-conversion rate.
200 mesh metallic silicon powder is the most important semiconductor material and is widely used in computers, microwave communications, optical fiber communications, solar power generation, etc. Scientists call the current era the silicon era. Metal silicon has excellent physical, chemical and semiconductor properties, so it has been quickly applied in semiconductor devices and developed rapidly. The traditional preparation of ultrapure and ultrafine silica powder easily produces impurities during the production process, which is not conducive to large-scale industrial production. There are often problems with fine but not pure, pure but not fine. Some processes are too complex and the production cost is high. At present, my country's source of ultra-pure and ultra-fine metallic silicon powder relies largely on imports, and it is particularly important to improve independent ultra-pure and ultra-fine silicon powder production equipment.
