Industry Silicon Metal 441 Grade For Metallurgical
Silicon Metal Description
The properties of Silicon Metal 411 are similar to germanium, lead and tin. Silicon, only second to oxygen, existed in the form of silicon dioxide or silicate, is extremely rich in the earth's crust and accounting for more than a quarter of the total weight of the earth's crust. It is mainly used for silicone production, non-ferrous alloy additives and making high purity semiconductor materials.
