The main raw materials of silicon metal are quartz, coke and silica, which are smelted at high temperature through electric furnace heating. Silicon metal is also known as industrial silicon, which is often used as an additive for non-ferrous alloy. In addition, Silicon metal is also used as an alloying agent in the production of silicon steel. In the process of smelting special steels and non-ferrous alloys, it can also be used as a good deoxidizer. The silicon metal can also be purified into monocrystalline silicon, which is widely used in the production of electronics and semiconductors, and has a wide range of uses.

Silicon metal has a dark gray luster, with high melting point, good heat resistance, high resistivity advantages. It also has good oxidation resistance.Generally, its particle size is 10 ~ 100MM or 2 ~ 25MM.
At present, the method used by the manufacturer to produce silicon metal is generally carbothermal method. By purchasing silica as raw material, using petroleum coke, charcoal, wood chips, low ash coal and so on as reducing agent, smelting at high temperature in the ore-thermal electric furnace, reducing silicon metal from silica.
If you want to get a higher silicon content of silicon metal, it is necessary to refine, remove its internal impurities, get purity of 99.7% ~ 99.8% silicon metal products.
Silicon metal can effectively improve the high temperature resistance, wear resistance and oxidation resistance of products. It is widely used in steelmaking furnaces.
silicon Metal is also used in the silicone chemical industry, for 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 others .
At the same time, through the purification process of silicon metal, monocrystalline silicon is produced, which can be widely used in integrated circuits and electronic components. In the metallurgical and casting industry, silicon metal is used as a non-ferrous alloy additive and silicon steel alloy agent, thus improving the hardenability of steel.
Adopts high-quality ton bags for packaging, to ensure the safety of goods transportation, according to customer requirements using wooden frame or iron drums for packaging, using land and sea transportation, high quality silicon 441 products will be transported to all parts of the world.
