Russia’s first large-scale manufacturing of polysilicon—1,800 tons

NITOL companies Usolie-Sibirsky Silicon and Usoliekhimprom in Usolie-Sibirskoe, Irkutsk Oblast, are setting up high-tech complexes where they will manufacture polycrystalline silicon.

Polycrystalline silicon (polysilicon) is the basic semiconductor material used in modern microelectronics, electric power, solar energy, and micromechanics. More than 80 percent of production of the world’s solar cells is based on polysilicon. Five countries provide most of the polysilicon production: the United States, Japan, Germany, Italy, and China.
