Silicon powder
Ultrapure silicon is mainly used for the production of electronic devices and circuits. Pure silicon is the main raw material for solar energy.
Monocrystalline silicon – in addition to electronics and solar energy, is used for the manufacture of gas lasers mirrors.
Metal compounds with silicon – silicides – are widely used in industry. Silicon compounds serve as the basis for the production of glass and cement.
Technical silicon finds the following applications:
raw materials for metallurgical industries: alloy component (bronze, silumin);
deoxidizer (in the smelting of iron and steel);
metal properties modifier or alloying element
for the production of solar cells;
and plastics.
