Preparation Features and Some Properties of Nickel Chloride Crystal Hydrates
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 crystallization 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 allowed to estimate the equilibrium faceting and optical spectra. A comparative analysis of the thermal stability of the obtained crystal hydrates 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 as compared to the nickel sulfate crystal.
