DESCRIPTION
Silicon Metal is a very important industrial product can be used in steel-making, cast iron, aluminum.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. Generally the diameter is 10-50mm,50-100mm,10-100mm or other sizes as customer’s request.
