Preparation and X-ray diffraction study of phosphate sulfates M2MgTi(SO4)(PO4)(2)

摘要

Phosphate sulfates M2MgTi(SO4)(PO4)(2) (M = alkali metal) prepared by the sol-gel technique with ethanol as salting-out agent were characterized by differential thermal analysis, electron probe microanalysis, and X-ray phase analysis. The crystal structure of the compounds synthesized (M = Na, K) was refined by powder X-ray diffraction. The phase stability of the phosphate sulfates under heating was examined.
