Abstract
Conditions are described under which a concentrated low-alkaline ammonium s olution of zirconium oxofluorocarbonate can be prepared by mixing zirconium oxofluoride, resulting from hydrolysis of technological (NH4)(3)ZrF7 solut ion, with solid ammonium hydrocarbonate. The precipitate isolated by evapor ating the solution was characterized by chemical, X-ray phase, and thermal analyses, and by IR spectroscopy.
