Summary
The solubility of CoSeO3-SeO2-H2O system in the temperature region 298-573 K was studied. The phase diagram of cobalt(II)selenites was drawn and the crystallization fields for the different phases were determined. Depending on the conditions for hydrothermal synthesis, CoSeO3×2H2O, α-CoSeO3×1/3H2O, β-CoSeO3×1/3H2O, CoSeO3, Co(HSeO3)2×2H2O and CoSe2O5 were obtained. The different phases were proved and characterized by chemical and X-ray analyses, as well as IR spectroscopy.
