Brief description |
| |
Cadmium has a melting point of 320.9°C, boiling point of 765°C, spcific gravity of 8.65 (20°C), and a valence of 2. Cadmium is a blue-white metal soft enough to be easily cut with a knife.

Uses of Cadmium |
| |
Cadmium is used in alloys with low melting points. It is a component of bearing alloys to given them a low coefficient of friction and resistance to fatigue. Most cadium is used for electroplating. It is also used for many types of solder, for NiCd batteries, and to control atomic fission reactions. Cadmium compounds are used for black and white television phosphors and in the green and blue phosphors for color television tubes. Cadmium salts have wide application. Cadmium sulfide is used as a yellow pigment. Cadmium and its compounds are toxic.
