Abstract
Lithium sodium sulfate, LiNaSO4, and lithium potassium sulfate, LiKSO4, have been prepared with yttrium sulfate, Y2(SO4)3, as a substituent over a concentration range up to 15 mol%. Raman spectra of the sulfate ion intramolecular modes suggest the formation of a new compound in the substituted materials. The possibility of substitutional stabilization of a higher temperature phase in the parent compounds is ruled out by comparison with the spectrum of the high temperature phase in each pure parent compound. A differential scanning calorimetry study of substituted LiKSO4 shows an endothermic process at 281°C not present in the pure compound. Powder X-ray diffractograms of the substituted LiKSO4 compounds indicate the presence of pure LiKSO4, pure Y2(SO4)3, and new peaks not attributable to either component. © 1993 Academic Press, Inc.
