Selenium consumption is high in metallurgy, electrolytic manganese is produced with the use of selenium. Selenium enhances machinability of stainless steel and certain types of copper alloys. In glass industry, selenium is used for glass colorizing/decolorizing. Selenium is consumed in semiconductor sector; it is used in manufacturing of electric current rectifiers, photocells, photographic exposure meters, solar cells, optical devices. Selenium is added to animal feed and fertilizers.
