Anwendungen & Verwendung
Beschreibung
Cadmium chloride is a colourless and odourless crystal. It is used for the preparation of cadmium sulphide, used as ‘cadmium yellow’, a brilliant-yellow pigment, which is stable to heat and sulphide fumes. Cadmium chloride has a high solubility in water and is a non-combustible solid, but the dust can be a moderate fire hazard when exposed to heat or flame or when reacted with oxidising agents. It is incompatible with bromine trifluoride, potassium oxidisers, zinc, selenium, tellurium, and hydrogen azide.
Verwenden
Cadmium Chloride is used in the preparation of the stable inorganic pigment cadmium sulfide (Cadmium Yellow). Cadmium Chloride treatment of thin film CDTe solar cells is used to produce high-efficienc y solar cells.. Cadmium Chloride is also used in the preparation of organocadmium compounds.
Herstellung & Synthese
synthetische
Cadmium chloride may be prepared by heating the metal with chlorine or hydrogen chloride gas. In the solution, it is formed by treating the metal or its salts, such as oxide, hydroxide, carbonate, or sulfide with hydrochloric acid:Cd + 2HCl → CdCl2 + H2CdO + 2HCl → CdCl2 + H2OCdCO3 + 2HCl → CdCl2+ H2O + CO2The solution is evaporated and crystallized to yield a hydrated salt. The hydrated salt yields anhydrous cadmium chloride upon heating under hydrogen chloride or when refluxed with thionyl chloride.Cadmium chloride also may be prepared by adding dry cadmium acetate to acetyl chloride in glacial acetic acid.
