High Silicon Low Iron Metal Silicon 3303, 441, 553, 2202 Particles from China Suppliers and Factory for Aluminum Plants

Semiconductor silicon is a high-purity metal silicon used to make semiconductor devices. It is sold in polycrystalline and single crystal forms, with the former being cheap and the latter being expensive. Divided into multiple specifications due to their different uses. According to statistics, in 1985, the world consumed about 500,000 tons of silicon metal, of which about 60% was used for aluminum alloys, less than 30% for organosilicon, about 3% for semiconductors, and the rest for steel smelting and precision ceramics.

According to the content of iron, aluminum, and calcium in metallic silicon, it can be classified into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101, etc.
