Cadmium metavanadate

Cadmium Metavanadate, Cd(V03)2, is obtained as brilliant, transparent, slender, yellowish needles by fusing a mixture of vanadium pentoxide, sodium bromide and cadmium bromide.4... 

Cadmium Polyvanadates.—Two are known, 2Cd0.3V20s.15H20 and Cd0.3Vs08.2HgO. The former is obtained by the action of cadmium sulphate on the corresponding barium salt,1 and the latter by the action of cadmium nitrate on ammonium metavanadate in the presence of acetic acid.2... 

The use of certain vanadium compounds as catalysts has been increasing. Vanadium oxy trichloride is a catalyst in making ediylene-propylene rubber. Ammonium metavanadate and vanadium pentoxide aie used as oxidation catalysts, particularly in the production of polyamides, such as nylon, in the manufacture of H>S04 by the contact process, in the production of phdialic and maleic anhydrides, and in numerous other oxidation reactions, such as alcohol to acetaldehyde, anthracene to anthraquinone, sugar to oxalic acid, and diphenylamine to carbazole. Vanadium compounds have been used for many years 111 die ceramics field for enamels and glazes. Colors are produced by various combinations of vanadium oxide and silica, zirconia, zinc, lead, tin, selenium, and cadmium. Vanadium intermediate compounds also are used in the making of aniline Mack used by the dye industry...
