Metal silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Industrial silicon is also used as an alloying agent for demanding silicon steel, a deoxidizer for smelting special steel grades and non-ferrous alloys. After being processed by a series of processes, industrial silicon can be drawn into monocrystalline silicon for use in the electronics industry.

The composition of metal silicon is mainly silicon, so it has similar properties to silicon. The properties of metal silicon are similar to those of germanium, lead and tin, and have semiconductor properties.

The classification of metal silicon is usually classified according to the content of three main impurities of iron, aluminum and calcium contained in the metal silicon component. According to the content of iron, aluminum and calcium in metal silicon, metal silicon can be divided into 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and other different grades.

Application

Silicon metal, in its pure form, is a grey metallically lustrous metalloid element. Metallurgical grade silicon is known as silicon metal because of its lustrous appearance.

Silicon is used mainly in the manufacture of silanes and silicones, as a "hardener" or alloying element to produce aluminium alloys, and in the manufacture of micro-processors and solar cells.

Silicon is also used as a secondary smelting additive in the manufacture of photonic devices and in the manufacture of industrial refractories.
