Description: Tellurium is a silvery-white, metallic-looking in bulk, but is usually obtained as a dark grey powder. It is a semi-metal. Tellurium burns in air or oxygen, is unaffected by water or HCl, but dissolves in HNO3. It is used in alloys to improve machinability, in electronics, and in catalysts.
