Popis:	An yttrium ammonium carbonate with the composition NH4Y(CO3)2 ∙ H2O has been prepared by reacting hydrated yttrium oxide with ammonium carbonate at 80°C. The synthesis process has been shown to proceed through crystallization of two intermediate phases: yttrium ammonium hydroxycarbonates differing in composition. The synthesized compounds have been characterized by X-ray diffraction, IR spectroscopy, differential scanning calorimetry, thermogravimetry, and chemical analysis. The first X-ray diffraction characteristics of NH4Y(CO3)2 ∙ H2O and crystallographic data for its unit cell have been presented. Thermal decomposition of the yttrium ammonium carbonate has been shown to yield cubic yttrium oxide in the form of fine powder.
