97 Silicon" typically refers to silicon metal with a purity level of 97%. Silicon metal is a critical raw material used in various industries, including the production of aluminum alloys, silicones, semiconductors, and solar cells.
Here are some key points regarding 97% silicon:
- Purity: 97% silicon indicates that the material is composed of approximately 97% pure silicon, with the remaining 3% consisting of impurities, such as iron, aluminum, calcium, and other elements.
- Applications: Silicon metal with 97% purity is commonly used in metallurgical applications, including the production of aluminum-silicon alloys for automotive and aerospace industries. It is also used as a deoxidizer and alloying agent in steelmaking processes to improve the mechanical properties of steel.
- Chemical Properties: Silicon is a semiconductor with excellent electrical conductivity and thermal stability. It exhibits properties such as high melting point, low density, and resistance to corrosion, making it suitable for various industrial applications.
- Production: Silicon metal is typically produced through the carbothermic reduction of silica (SiO2) using carbonaceous materials such as coal, coke, or wood chips in an electric arc furnace. The process involves high-temperature reactions to produce molten silicon, which is then cooled and solidified into ingots or granules.
- Quality Standards: The quality of silicon metal is crucial for its performance in different applications. Manufacturers adhere to strict quality standards and specifications to ensure the desired chemical composition, particle size distribution, and physical properties of the product.
- Availability: Silicon metal with 97% purity is readily available from various suppliers and producers worldwide. It is supplied in different forms, including ingots, granules, and powder, to meet the specific requirements of different industries.
Overall, 97% silicon metal serves as a versatile and essential material in various industrial processes, contributing to the production of high-quality alloys and products across different sectors.
