SELENIUM

selenioSelenium is a non-metallic chemical element has properties similar to sulfur and tellurium. Selenium is found in a number of forms including a crystalline form of selenium called gray "metallic".

The latter form takes more electricity to light the dark and is used in photocells. Because of its photovoltaic and photoconductive properties, selenium is used in electronics, such as photocells, light meters and solar cells. It is also used in the glass to remove the color and give a red color to glasses and enamels.
