Silicon Metal Is Produced By Reduction

Silicon Metal is produced by reduction of silica, so it is also called industrial silicon, crystalline silicon, is a new product for nearly half a century. Mainly exported to Japan, the United States, Europe, Australia, India, South Korea, Malaysia, Hong Kong, Taiwan, Canada, Mexico, Argentina and other countries and regions. Due to the high power consumption of 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 after use (many factories will use silica and charcoal after water washing before feeding). Calcium is controlled mainly through the elimination of chlorine gas or oxygen. Oxygen also has a certain effect on the removal of iron and aluminum. Silicon metal used in electronics and chemicals also has requirements for chromium, bismuth, lead, manganese, titanium, 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.
