Selenium (Se)
- Description
Description
Selenium is a metalloid (an element intermediate in properties between the metals and the nonmetals). It is in metallic form with gray color. Selenium has diverse applications in industries from metallurgy, chemicals and pigments to electronics, agriculture and animal feed. It is also popularly used in glass making
High-purity Selenium is used in vacuum-deposition, in solar industry to produce CIGS solar cells and in semiconductor industry to produce Zinc Selenide for infrared optics. It is also used as source materials for molecule bean epitaxial applications in semiconductor researches and productions.
