2. Manufacturing semiconductor materials: Industrial silicon is an important raw material for manufacturing semiconductor materials. Through processing, crystal growth and photolithography, it can be made into silicon wafers, silicon chips and other materials for the production of integrated circuits, solar cells, photovoltaic elements, etc.
3. Manufacturing glass and ceramics: Silicon is one of the main components of glass and ceramics. Industrial silicon is used to manufacture various types of glass and ceramic products, such as glassware, glass fiber, ceramic factory bricks, etc.
4. Manufacturing chemicals: Industrial silicon can be used to produce chemical products such as silicone resin, silica gel, silicone oil, etc. These chemicals are widely used in machinery, automobiles, construction, electronics and other industries.
5. Manufacturing refractory materials: Silicon is an excellent refractory material. Industrial silicon can be made into refractory materials such as aluminum silicate and magnesium silicate, which are used for lining and thermal insulation of high-temperature industrial equipment such as steelmaking, smelting, and glass kilns.
6. Manufacturing insulation materials: Industrial silicon can be used to manufacture various insulation materials, such as silicate fiber, silicone insulation board, etc., which are used in construction, aerospace, nuclear energy and other fields.
7. Manufacturing cosmetics and medical devices: Industrial silicon can be used to produce materials such as silicone and silicone rubber. These materials have excellent anti-aging, wear resistance, high and low temperature resistance and other properties, and are widely used in cosmetic packaging, medical devices and prosthetic implants.
8. Manufacturing silicate products: Industrial silicon can be used to produce silicate cement, silicate sheets, silicate coatings and other products, which are used in construction, decoration, home furnishing and other fields.
In short, industrial silicon is an important industrial raw material with a variety of uses. It is widely used in various fields such as metallurgy, electronics, construction, chemical industry, and medical care, and plays an important role in economic development and social progress.
