Cadmium


Rechargeable batteries
Anti-corrosion protections: bolts and nuts
Regulation bars in nuclear reactors
Red and yellow pigment

The major use of cadmium is for plating articles to form a protective coating (mainly on iron and steel); most of this plating is done by electroplating. An in important use for cadmium is in the nickel-cadmium storage battery. Cadmium is used in many alloys such as bearing metals, solders, electrical conductor, fusible metals and jewelry.

Cadmium absorbs low energy (thermal) neutrons readily; and, when rods of cadmium are inserted in a nuclear reactor, this absorption of thermal neutrons provides a means for controlling the fission process.

In the electronics industry, cadmium is used in television phosphorus and in photovoltaic cells, radiation detection devices, infrared windows, and photosensitive devices.
