Molecular formula: Cd(NO
3)
2.4H
2O
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
