Selenium is a nonmetallic chemical element, with properties that are intermediate between sulfur and tellurium. Selenium appears in a number of allotropic forms: the most popular are a red amorphous powder, a red crystalline material, and a gray crystalline metallike form called metallic selenium.
The main commercial uses of selenium are additives to glass and pigments for ceramic, paint and plastics. As selenium has both photovoltaic and photoconductive actions, it is also often used in photocells, solar cells and photocopiers.
Selenium salts are toxic in large amounts, but trace amounts are necessary for cellular function in many organisms, and is an ingredient in many multi- vitamins and other dietary supplements, including infant formula.
