Metallurgical silicon (also known as silicon metal) is recognised by the European Commission as a Critical Raw Material (CRM) due to its economic importance in a wide range of applications, many of which have no possible substitutes. CRMs are defined as products that have a significant impact on the EU economy and a high risk of supply shortages. Among them, photovoltaic (PV) thin cells, wind turbine generators and lithium-ion batteries are among the most relevant applications of CRMs for green technologies.Silicon Metal is processed by excellent industrial silicon and including full varieties. Used in electro, metallurgy and chemical industry. It is silver gray or dark gray with metallic luster, which be of high melting point, good heat resistance, high resistivity and superior oxidation resistance. Metal Silicon is a very important industrial product can be used in steel-making, cast iron, aluminum (aviation, aircraft & automobile parts production), and silicon optoelectronic device and many other industries. It’s known as the “salt” of modern industries. Metal silicon is made from quartz and coke in electric heating furnace smelting products. The main ingredient of silicon content is about 98%. The rest of impurities is iron, aluminum and calcium etc.
