Cadmium metal is silver white transition metal, which is available in ingots, rods, sticks, plates, powders, targets and granules. It is soft and toxic, which exist in zinc ore. Cadmium and zinc both are battery material. Cadmium granules slowly oxidize in moist air and lose metal luster. When heating its surface form oxide layer (CdO). With heating cadmium powder can directly react with halogen and other non-metallic elements as sulfur, selenium phosphorus. Cadmium ingot is high purity material for semiconductor and reagents.
