Abstract
Double rare earth(III) monomethylammonium sulfates with general empiri cal formula CH3NH3Ln(SO4)2.3H2O (Ln = La-Er and Y) were synthesized an d examined by X-ray powder diffraction, TG, DTG and DTA in the tempera ture range from 25-degrees-C to 700-degrees-C, and chemical analysis. It was found that these compounds are isomorphous and decompose to rar e earth sulfate at 700-degrees-C.
