DESCRIPTION
Metallurgical silicon metal (also known as industrial silicon or silicon metal) is a raw material used in various industries for producing silicones, semiconductors, and aluminum alloys. It is a gray or silver-colored metallic substance with a high melting point and a low density.
Metallurgical silicon metal is made by reducing silica (SiO2) with carbon in an electric arc furnace. The process involves heating a mixture of silica, carbon, and other additives to very high temperatures. The resulting silicon metal is then crushed and refined to remove impurities.
Metallurgical silicon metal typically has a silicon content of 98-99%, with trace amounts of other elements such as iron, aluminum, and calcium. The purity of the silicon metal is important in determining its suitability for different applications. For example, higher-purity silicon metal is needed for producing semiconductors, while lower-purity grades may be suitable for use in aluminum alloys.
Metallurgical silicon metal is a critical material for many industrial applications, and its demand is driven by the growth of the electronics, automotive, and construction industries.
