Silicon Metal
Industrial silicon, also known as quasi-metallic silicon, is a
commercial name that appeared in the mid-1960s. It is produced by
smelting silicon stone and carbonaceous reducing agents in a mine
furnace, with the main component, silicon, accounting for about 98%
of its content (in recent years, metallic silicon with a Si content
of 99.99% is also listed), and the remaining impurities include
iron, aluminum, calcium, etc.
Industrial silicon is classified into various specifications
according to its different uses. Based on the content of iron,
aluminum, and calcium in quasi-metallic silicon, it can be divided
into different brands such as 553, 441, 411, 421, 3303, 3305, 2202,
2502, 1501, and 1101. The additional products of quasi-metallic
silicon include microsilica, edge silicon, black silicon, and
metallic silicon slag, among which microsilica, also known as
silicon dust, is widely used in the refractory material and
concrete industries.
