Specification

Application

Electrolytic manganese industry: Selenium is added in the production of electrolytic manganese to enhance the current efficiency.
Glass industry: Selenium de-colors glass by neutralizing the green color due to the presence of iron. If a red color is desired cadmium sulphoselenide is added. Selenium is also used in the production of privacy glass.
Agriculture: Since selenium is an essential micronutrient for animals it is used in premix for feed additives. It is also added to some special blends of fertilizers.
Metallurgy: Selenium is added to improve the machinability of carbon steel, stainless steel and copper. It acts as a grain refiner in the grids of low-maintenance lead-acid batteries.
Pigment: Cadmium sulfoselenide compounds are added in plastics, glass, ceramics and paints for red or orange color.
Electronic/electrical: Due to infrared light transparency, Selenium is used in windows for infrared optical devices (lenses for CO₂ lasers).
In solar cells selenium is used in CIGS, CIS and CdSe.

It is also used in some smaller electronic applications like thermoelectric devices. Lithium-selenium batteries are one of the most promising systems for energy storage but is still in an early stage of development.
