The main use of silicon metal
Metal silicon is mainly used in aluminum alloy industry, silicon aluminum alloy is the largest amount of silicon alloy. Si-Al alloy is a kind of strong compound deoxidizer, which can improve the utilization rate of deoxidizer, purify the liquid steel and improve the quality of steel when replacing pure aluminum. Aluminum used in automobile and other industries has a considerable demand for industrial silicon, so the development of a region or a country's automobile industry has a direct impact on the rise and fall of industrial silicon market.
Silicon metal is mainly used in the additive of non-ferrous alloy, silicon metal is also used as an alloying agent for strict requirements of silicon steel, smelting special steel and non-ferrous alloy deoxidizing agent.
Silicone metal is mainly used in the chemical industry, for the production of silicone rubber, silicone resin, silicone oil and other silicone, silicone rubber elastic, high temperature resistance, used for the production of medical supplies, high temperature resistance gaskets, etc.. Silicone is used in the production of insulating paint, high temperature paint, etc. Silicone oil is a kind of oil, its viscosity is affected by the temperature is very small, used in the production of advanced lubricants, glazing agent, fluid springs, dielectric liquids, etc., can also be processed into a colorless and transparent liquid, as a senior waterproofing agent sprayed on the surface of buildings.
The silicon metal is purified by a series of processes to produce polycrystalline silicon and monocrystalline silicon, which can be used in photovoltaic industry and electronics industry. Crystal silicon cells are mainly used in solar rooftop power stations, commercial power stations and urban power stations with high land cost. Currently, they are the most mature and widely used solar photovoltaic products, occupying more than 80% of the world photovoltaic market, and their demand for silicon metal grows significantly. Modern large integrated circuits are almost made of high purity quasi - metallic silicon, and high purity quasi - metallic silicon is also the main raw material for the production of optical fiber, it can be said that quasi - metallic silicon has become the basic pillar industry in the information age.
