Sažetak
On evaporation at room temperature of an aqueous mixture of Ln(SO4)3 (Ln=Ho, Yb, Lu) and (HOCH2CH2NH#)2SO4 in a molar ratio 1:16, crystal products were obtained. There were identified by means of x-ray powder diffraction and found to be isostructural. The results of elemental analysis and the mass losses by TG analysis indicated the formation of double sulfates. Their thermal decomposition in static air in temperature range from ambient up to 1173 K took place in a similar way, mainly in three steps which were not well defined. Oxysulfates were the final products of the termal decomposition.
