Metal Powder

Cadmium powder is a lustrous, silver-white, ductile and very malleable metal. The metal is soft and its surface has a bluish tinge. So it is very soft and easily cut with a knife, however, it tarnishes in air. It is soluble in acids while not in alkalis. It is similar in many respects to zinc but it produces more complex compounds. Cadmium is utilized in Ni-Cd batteries and cadmium sulfide is employed as a yellow pigment. Moreover, cadmium selenide is applied as a red pigment, often called cadmium red.

Cadmium powder is used mainly for coatings and plating. It is also employed as stabilizers for plastics. Cadmium has been employed particularly to electroplate steel where a film of cadmium provides complete protection against the sea. Cadmium has the capability to absorb neutrons, so it is employed as a barrier to control nuclear fission.

Cadmium powder has been used in some nations to coat steel through electroplating. Cadmium sulfide and cadmium sulfoselenide are still utilized to a limited extent as color pigments in plastics and in various types of paints. Cadmium stearate is used as a stabilizer in plastics due to its ability to stiffen copper and increment its mechanical resistance at elevated temperatures.

Cadmium powder is used in copper-cadmium alloys, which are used in items, for instance, automobile radiators. Cadmium may act as an electrode component in alkaline batteries; this application is one of the most important current uses of Cadmium. In addition, cadmium is also used in silver solders and welding electrodes and cadmium telluride are increasingly used in solar panels.

Cadmium powder was often used to protect the surfaces from corrosion so it is employed to electroplate steel. It is still used today to protect the critical components of airplanes and oil platforms. In the earlier uses of cadmium involved phosphors in cathode ray tube color TV sets, and different color pigments such as yellow, orange and red. Cadmium absorbs neutrons so it is used in rods in nuclear reactors to control atomic fission.
