Selenium (Se)

Amorphous selenium is either a reddish powder, a gray metallic-looking solid, or a black, vitreous solid. This element resembles sulfur in its various forms and in its compounds. Selenium has many electrical properties, both photovoltaic, where light converts to electricity, and photoconductive, where electrical resistance decreases with increased illumination. It can also convert AC electricity to DC electricity.

Purity: 99.5% to 99.99%
Typical Applications

Selenium has commercial uses in specialty glassmaking, i.e., the production of light-sensitive surfaces and pigments for plastics, glass, ceramics, and paint. Selenium’s photovoltaic and photoconductive properties make it useful in photocells and solar cells. Selenium is used in several types of DC power surge protectors and rectifiers. It is used as an additive to make stainless steel.

Packaging Options

Drums, bulk bags or loose bulk

Sustainable Qualities

Selenium is a naturally occurring element used in various applications, including electronics, photovoltaic cells, and glass production. Selenium is a highly sustainable material, as it is abundant in the earth’s crust and is extracted through mining. Additionally, Selenium is fully recyclable, making it a valuable contributor to a circular economy. By recycling Selenium, manufacturers can reduce their dependence on virgin materials, reduce waste, and conserve resources.
