Introduction to silicon metal powder:
Silicon metal powder is silicon metal (industrial silicon) after grinding and processing of silicon powder.
Metallic silicon, also known as crystalline silicon or industrial silicon, is primarily used as an additive to non-ferrous alloys.Industrial silicones are also used as alloys for demanding silicon steels, deoxidizers for special steels and non-ferrous alloys.After a series of processing processes, industrial silicon can be pulled into a single crystal silicon for use in the electronics industry.
Silicon metal property ,Metallic silicon is composed mainly of silicon, so it has similar properties with silicon.The properties of metallic silicon and germanium, lead, tin similar, with semiconductor properties.
Silicon metal classification
Silicon metal is usually classified according to the content of iron, aluminum and calcium, the three main impurities contained in silicon metal.According to the content of iron, aluminum and calcium in silicon metal, silicon metal can be divided into 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and other different grades.
Use of metallic silicon powder
1. Metallic silicon powder is widely used in refractory materials and powder metallurgy industries to improve the product's resistance to high temperature, wear and oxidation.Its products are widely used in steel furnace, furnace, kiln.
2. In the organic silicon chemical industry, metal silicon powder is the basic raw material for organic silicon polymer synthesis, such as the production of silicon monomer, silicone oil, silicone rubber preservatives, so as to improve the product's high temperature resistance, electrical insulation, corrosion resistance, corrosion resistance, waterproof and other characteristics.
3. Silicon metal powder is made into monocrystalline silicon by pulling, and the silicon wafers made by processing are widely used in high-tech fields, which are essential raw materials for integrated circuits and electronic components.
4. In metallurgical casting industry, metallic silicon powder is used as non-ferrous alloy additive and silicon steel alloy agent to improve the hardenability of steel.Industrial silicon powder can also be used in some metal reductants, for new ceramic alloys.
