Main Uses Of Industrial Silicon

In the aluminum alloy industry, silicon aluminum alloy is the most widely used silicon alloy. Silicon aluminum alloy is a kind of strong composite deoxidizer, which can improve the utilization rate of deoxidizer by replacing pure aluminum in the steelmaking process, and can purify molten steel and improve the quality of steel. The demand for industrial silicon for aluminum used in automotive and other industries is quite large, so the development of the automotive industry in a region or country has a direct impact on the rise and fall of the industrial silicon market.

As an additive for non-ferrous alloys, industrial silicon is also used as an alloying agent for silicon steel with strict requirements, and a deoxidizer for smelting special steel and non-ferrous alloys.

In the chemical industry, it is used to produce silicone rubber, silicone resin, silicone oil and other silicones. Silicone rubber has good elasticity and high temperature resistance. It is used to make medical supplies, high temperature gaskets, etc. Silicone resins are used in the production of insulating paints, high temperature coatings, etc. Silicone oil is an oily substance whose viscosity is little affected by temperature. It is used in the production of advanced lubricants, glazing agents, fluid springs, dielectric liquids, etc. It can also be processed into colorless and transparent liquids and sprayed as advanced waterproofing agents. on the building surface.

Industrial silicon is purified by a series of processes to generate polysilicon and monocrystalline silicon, which are used in the photovoltaic industry and the electronics industry. Crystalline silicon cells are mainly used in solar rooftop power stations, commercial power stations and urban power stations with high land costs. They are currently the most mature and widely used solar photovoltaic products, accounting for more than 80% of the world photovoltaic market. The growth rate is obvious. Almost all modern large-scale integrated circuits are made of high-purity metalloid silicon, and high-purity metalloid silicon is also the main raw material for the production of optical fibers. It can be said that metalloid silicon has become a basic pillar industry in the information age.
