Аннотация

The temperature dependence of solubility in the NiCl2-H2O system in the temperature range of 25–60°C has been studied. The temperature ranges of crystallisation of NiCl2·6H2O and NiCl2·4H2O compounds have been determined. Single crystals of nickel chloride hexahydrate and tetrahydrate have been obtained, the size and quality of which have allowed the equilibrium faceting and optical spectra to be estimated. A comparative analysis of the thermal stability of the crystal hydrates obtained was carried out. It was found that the transparency band in the short wavelength range for nickel chloride crystals is shifted to the long wavelength range compared to the nickel sulphate crystal.
