"Metal silicon" is a product name that appeared 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. Metallic silicon is a product smelted from quartz and coke in an electric furnace.
The main component silicon content is about 98% (99.99% Si content is also included in metallic silicon), and the remaining impurities are iron, aluminum, calcium, etc. . Semiconductor silicon is a high-purity metallic silicon used to make semiconductor devices. It 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.
