Selenium is a nonmetal (more rarely considered a metalloid) with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic.
Properties:
Melting point 494 K (221 °C, 430 °F)
Boiling point 958 K (685 °C, 1265 °F)
Density (near r.t.) gray: 4.81 g/cm3/alpha: 4.39 g/cm3/vitreous: 4.28 g/cm3
Application
The chief commercial uses for selenium today are glassmaking and pigments. Selenium is a semiconductor and is used in photocells. Applications in electronics, once important, have been mostly replaced with silicon semiconductor devices. Selenium is still used in a few types of DC power surge protectors and one type of fluorescent quantum dot.
