DESCRIPTION
Metal silicon from ZhenAn 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.
Silicon Metal lump was produced in electric heating furnace by quartz and coke. Quartz will be redox and became molten silicon liquid. After cooling, it will be solid as we see. The primal silicon metal lump is very large.
