Silicon metal, known as crystalline silicon or industrial silicon, is primarily used as an additive in non-ferrous alloys.Silicon metal is made by smelting silica and carbonaceous reducing agent in the ore furnace. The main component of silicon metal is silicon element, whose content is about 98%, and the other impurities are iron, aluminum, calcium, etc.
According to the content of iron, aluminum and calcium in silicon metal, silicon metal can be divided into 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and other different grades.
The grades and chemical composition of silicon metal are as follows.
