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. Silicon Metal 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.
According to the content of iron, aluminum and calcium in silicon metal, silicon metal can be divided into different grades, such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101.
