Silicon Metal
Silicon Metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. It is a product made by smelting quartz and coke in an electric furnace. The main element silicon content is about 98%, and the remaining impurities are iron and aluminum, Calcium, etc.
