Product Description
The properties of silicon metal 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.
Performance Application
Silicon metal grade 441 can be used as the raw materials of silicone, polysilicon and aluminum alloy industries.
Silicon Metal Uses
1. Silicone field: silicone oil, silicone rubber, silane coupling agent, etc.
2. Polysilicon field: solar photovoltaic and semiconductor materials
3. Aluminum alloy field: automobile engine, wheel hub, etc.
