General description

Cadmium is a naturally occurring element found in the earth′s crust. Usually, it is found as a mineral combined with oxygen (cadmium oxide), chlorine (cadmium chloride), or sulfur (cadmium sulfate, cadmium sulfide). Cadmium is a relatively rare element that is not found in its pure form in nature. It is possible to combine cadmium with several nonferrous metals to form alloys with useful commercial properties. The five main applications of cadmium are:
  • nickel-cadmium battery electrodes
  • plastic, ceramic, and glass pigments
  • polyvinyl chloride (PVC) stabilization against light and heat
  • engineering coatings for steel and other nonferrous metals
  • a component of several specialized alloys.

Application

Cadmium granules is used to reduce nitrate to nitrite.
