Silicon metal 2202 is a grade of metallic silicon, which is divided according to the different levels of iron, aluminum and calcium. The metallic silicon is silver-gray crystalline, hard and brittle, and is smelted by quartz stone containing more than 98.5% SiO2 and other materials. Industrial silicon is widely used as a basic industrial raw material, mainly used in the production of organic silicon, polysilicon, in aerospace, aviation, electronics, organic chemical industry, smelting, thermal insulation refractory and other industries and fields have a wide range of applications. Features and usage： * Widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear resistance and oxidation resistance. * In the organosilicon chemical industry, industrial silicon powder is the basic raw material for the formation of organosilicon polymer. * Industrial silicon powder is sublimated into monocrystalline silicon, which is widely used in highttech field as an essential raw material for integrated circuit and electronic element.
