Cadmium oxide is an inorganic compound with the formula CdO. It is one of the main precursors to other cadmium compounds. It crystallizes in a cubic rocksalt lattice like sodium chloride, with octahedral cation and anion centers. It occurs naturally as the rare mineral monteponite.
Cadmium oxide can be found as a colorless amorphous powder or as brown or red crystals.Cadmium became an important metal in the production of nickel-cadmium (Ni-Cd) rechargeable batteries and as a sacrificial corrosion-protection coating for iron and steel.
Cadmium oxide is used in cadmium plating baths, electrodes for storage batteries, cadmium salts, catalyst, ceramic glazes, phosphors, and nematocide. Major uses for cadmium oxide are as an ingredient for electroplating baths, optoelectronic devices, and in pigments.
carbon oxide moleculeThey are equal and opposite, so they cancel (the centers of partial-negative and partial-positive charge in the molecule are at exactly the same place). Thus the carbon dioxide molecule as a whole is nonpolar, even though it contains polar bonds.
