In what industries is metallic silicon mainly used?
1. In the aluminum alloy industry, replacing pure aluminum in the steelmaking process can improve the utilization rate of deoxidizer, purify molten steel, and improve the quality of steel. Aluminum used in automobile and other industries has a considerable demand for industrial silicon, so the development of the automobile industry in a region and country has a direct impact on the rise and fall of the industrial silicon market.
2. Additive for non-iron-based alloys. Industrial silicon is also used as an alloying agent for silicon steel with strict requirements and as a deoxidizer for smelting special steel and non-ferrous-based alloys.
3. Industrial silicon is purified through a series of processes to produce polycrystalline silicon 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 mature technology and widely used solar photovoltaic products, and their demand for metallic silicon is growing significantly. Modern large-scale integrated circuits are almost made of high-purity metallic silicon, and high-purity metallic silicon is also the main raw material for the production of optical fibers. It can be said that metallic silicon has become an industry in the information age.
