MW:**2.4

MP:**0.9oC

Relative density:8.**2

Specification

Cadmium is a shiny silver-white metal. There toughness and ductility. Cadmium oxide in moist air slowly and lost metallic luster, brown when heated oxide layer formed on the surface. High temperature reacted strongly to cadmium and halogens to form a halogenated cadmium [1]. Can also be a direct chemical combination with the sulfur to produce CdS. Cadmium can be dissolved in acid, but does not dissolve in alkali. Cadmium oxidation state of *1, *2. Cadmium oxide and cadmium hydroxide solubility of very small, they are soluble in acid, but does not dissolve in alkali. Cadmium can form a variety of complex ion, such as Cd (NH3), Cd (CN), CdCl, etc.. Greater toxicity of cadmium was cadmium polluted air and food that cause serious harm to human body, due to cadmium poisoning in Japan, there have been "Itai-itai disease."

Uses

For electricity industry and manufacturing alloy, etc.; can be made atomic reactors to absorb neutrons stick.With the high oxidation potential of  Cadmium, it can be used as iron, steel, copper and the protective film is widely used in electroplating, on and used rechargeable batteries, television picture tube, the yellow pigment and as a plastic stabilizer. Cadmium compounds are used in insecticides, fungicides, pigments, paints, etc. of the manufacturing sector.
