Abstract
Fluorination of oxides of rare earths using ammonium hydrogen fluoride at room temperature gave new compounds [NH4]3MF6•nH2O, where M = Y, La, Nd, and Pr. In the case of cerium, [NH4]4CeF8 is formed. The course of thermal decomposition of all these compounds is studied by thermogravimetry/differential thermal analysis (TG/DTA) and X-ray powder diffraction (XRD). Keywords: hexafluoro metallates, rare earths, ammonium hydrogen fluoride, thermal decomposition, X-ray diffraction.Keywords
