Silicon metal is produced by reducing silica, so it is also called industrial silicon and crystalline silicon. It is a new product in the past half a century and is mainly exported to Japan, the United States, Europe, Australia, India, South Korea, Malaysia, Hong Kong, Taiwan, and Canada. , Mexico, Argentina and other countries and regions. Due to the extremely high power consumption for smelting metal silicon, the market price of metal silicon is correspondingly high. The main impurities in metal silicon are iron, aluminum and calcium, which need to be strictly controlled in production. At present, the control of iron and aluminum mainly adopts the inspection of silica and charcoal before feeding.

Silica with high iron and aluminum content cannot be used. Charcoal needs to be strictly selected before use (many factories wash silica and charcoal with water before use). The control of calcium mainly adopts chlorine gas or oxygen to get rid of. Oxygen also has a certain effect on removing iron and aluminum.

Metal silicon used in electronics and chemical industry also has requirements for chromium, banknotes, lead, manganese, chromium, phosphorus, copper, and carbon. Silicon has semiconductor properties. Crystalline silicon has a metallic luster and a bright gray appearance. It is very stable at room temperature, and only very active fluorine can be directly combined with it to form silicon tetrafluoride.

Silicon generated at high temperature can also be directly combined with excess carbon to form silicon carbide. When smelting aluminum alloy, add a small amount of pure
