Product Description
Silicon metal is an industrial material with high-purity silicon as the main component, which is widely used in many fields. It is smelted from quartz and coke in an electric furnace and has a high melting point, good electrical conductivity and oxidation resistance. In the metallurgical field, silicon metal is used as an additive for iron-based alloys to improve the hardenability of steel; In the chemical industry, it is the basic raw material for the production of silicon materials; In the semiconductor industry, silicon metal can be used to make monocrystalline silicon, which is a key raw material for integrated circuits and electronic components. In addition, it is also used in the production of refractory materials and high-temperature materials to meet different industrial needs.
Silicon metal is an important industrial raw material, the main component is silicon, the purity can reach 98%-99%. It is made by melting quartz and coke in a submerged arc furnace and has a high melting point, high thermal stability and good electrical conductivity. Silicon metal is used as an additive in metallurgy and casting to improve alloy properties; It is used as a basic raw material in organic silicon chemical industry for the production of silicone oil, silicone rubber and other materials; In the semiconductor industry, silicon metal is used to make monocrystalline silicon, which is the core raw material for integrated circuits and electronic components. In addition, it is used in the production of refractory materials and high-temperature materials, which are widely used in several industrial fields.
