摘要：
A method has been developed for the synthesis of single-phase sulfate-phosphates, which provides keeping from sulfur losses by its binding to sulfate with a high decomposition temperature. The thermally stable sulfate-phosphate Pb2Mg2(PO4)(2)SO4 was studied using X-ray diffraction, IR spectroscopy, DTA, and electron probe microanalysis. According to the results of the study by the Rietveld method, this compound belongs to the eulytite structural type (space group I43d). When the temperature changes, its crystals expand isotropically without polymorphic transitions.
