Selenium Metal & Powder
Designations:
Chemical Name: Selenium
Chemical Formula: Se
Description:
Amorphous selenium is either a reddish powder or a black, vitreous solid; crystalline selenium is either red or gray, depending on the crystal structure. This element resembles sulfur in its various forms and in its compounds. Selenium has many electrical properties, being both photovoltaic, where light converts to electricity, and photoconductive, where electrical resistance decreases with increases illumination. Below its melting point, selenium is p-type semiconductor.
