镉的硝酸盐

Molecular formula: Cd(NO3)2.4H2O Molecular weight: 308.482 Physicochemical properties: 1) Cadmium nitrate tetrahydrate is a colorless rhombic system crystal 2) Specific density: 2.45 3) Melting point 59.5°C. The tetrahydrate will convert into anhydride when is put into a drier or heated to 70 80°C. It will emit nitrogen oxide and turn into cadmium oxide when heated as high as 360°C. The tetrahydrate are very soluble in water, and also soluble in ethanol and acetone. It exhibits hygroscopic property 4) Cadmium nitrate is a strong oxidizer and toxic 5) Application and usage: cadmium nitrate is primarily used as colorant for glass and ceramics, emulsifier for photographic film and as analytical reagent. In addition, it also finds uses in preparation of other cadmium salts and cadmium oxide, as well as producing catalysts, batteries and drugs containing cadmium.
