The effects of the nature and concentration of bases, as well as the reactants ratio and the process temperature on the properties of zirconium hydroxides synthesized via heterophase conversion of zirconium oxychloride have been studied. An optimal concentration range of the alkalis for the transformation of the precipitates from a gel-like state to a crystal-like one has been established. The transition process was found to be accompanied by a significant decrease of the apparent volume. The crystal-like zirconium hydroxide synthesized during the study inherited the morphological features of the initial zirconium oxychloride that can be considered as an anamorphosis phenomenon.
