THE INFLUENCE OF NATURE OF FLUOROCIRCONATES OF ALKALINE ELEMENTS AND AMMONIUM ON IT IS HETEROPHASE CONVERSION INTO ZIRCONIUM HYDROXIDE BY KOH SOLUTION
The process of heterophase conversion of fluorozironates of alkaline elements and ammonium of different composition with stoichiometric and superstoichiometric amounts of 2.7 M KOH at room temperature has been studied. The sequence of changes in the reactivity of fluorozirconates has been determined: K2ZrF6 << (NH4)3ZrF7 <(NH4)2ZrF6 <K3ZrF7 <Cs2ZrF6.
