Silicon metal is an industrial basic material made from quartz and coke in a high-temperature electric furnace. It contains about 98% silicon and a small amount of impurities such as iron, aluminum, and calcium. Its production is through a carbon thermal reduction reaction to generate molten silicon liquid, which is cooled to form blocks or broken into powder.
As the “salt” of modern industry, silicon metal is widely used in metallurgy (steel deoxidation, aluminum alloy), chemical industry (organic silicon, polysilicon), photovoltaics and semiconductors. With its purity classification (industrial grade to electronic grade) and morphological diversity, it has become the core raw material supporting high-end manufacturing and green energy, and has penetrated into every link from traditional industry to cutting-edge technology.
