Cadmium ( Cd - 320.9°c )

 

Cadmium is a lustrous, silver-white, ductile, very malleable metal. Its surface has a bluish tinge and the metal is soft enough to be cut with a knife, but it tarnishes in air, and has both high electrical and thermal conductivity

Cadmium is used to a small extent as coatings (electroplating) to protect metals such as iron. The metal is a component of some specialist alloys including solders and alloys with low coefficients of friction and good fatigue resistance. Cadmium is a component of Ni-Cd batteries. Cadmium is used in some control rods and shields within nuclear reactors. Also Cadmium metal and cadmium compounds are used as pigments, stabilizers.
