Silicon metal is a product made by smelting quartz and coke in an electric furnace. The main component of silicon is about 98% (Si content of 99.99% is contained in silicon metal), and the remaining impurities are iron, aluminum, calcium, etc. Semiconductor silicon is used to manufacture high purity silicon metal for semiconductor devices. The classification of metal silicon is generally based on the content of the three main impurities of iron, aluminum and calcium contained in the metal silicon component, and depending on the content of iron, aluminum and calcium in metal silicon, metal silicon is 553, 441, 411, 421, It can be divided into different specifications like 3303, 3305, 2202, 2502, 1501, 1101, etc.
