Pure Silicon Metal
Main Introduction To Metallic Silicon
"Metal silicon" (also called industrial silicon in our country) is a product name that emerged in the mid-1960s. Its emergence is related to the rise of the semiconductor industry. The common international method is to divide commercial silicon into metallic silicon and semiconductor silicon.
Single Crystal Silicon Metal
Metallic silicon is sold in polycrystalline and monocrystalline forms. The former is cheap and the latter is expensive. It is divided into various specifications due to different uses. According to statistics, in 1985, the world consumed about 500,000 tons of metallic silicon, of which about 60% was used for aluminum alloys, less than 30% was used for organic silicon, about 3% was used for semiconductors, and the rest was used for Steel smelting and precision ceramics, etc.
What Is The Application Industry Of Metal Silicon Blocks?
1. Silicone field: silicone oil, silicone rubber, silane coupling agent, etc.
2. Polycrystalline silicon field: solar photovoltaic and semiconductor materials.
3. Aluminum alloy field: automobile engines, wheels, etc.
Polysilicon
Silicon is the raw material for ultrapure silicon in the electronics industry. Electronic devices made of ultrapure semiconductor single crystal silicon have the advantages of small size, light weight, good reliability and long life. High-power transistors, rectifiers and solar cells made from silicon single crystals doped with specific trace amounts of impurities are better than those made from germanium single crystals.

Raw materials for chemical silicon production In the production of chemical silicon, raw materials are a prerequisite for good operations. Quartz rocks are used as raw materials for the production of chemical metal silicon, and low-ash carbonaceous materials are used as reducing agents. The raw materials for producing chemical silicon by the electric furnace method mainly include silica and carbon raw materials. The carbon raw materials are mainly petroleum coke, including high-quality anthracite or charcoal, which can also be mixed in to increase the specific resistance of the charge. The raw materials are required to have the necessary purity and good reactivity in order to meet product specifications.
