Synthesis of Alpha-NaFeO2-Type LiYS2 by an Ion-Exchange Reaction

Abstract

LiYS2 with the hexagonal alpha-NaFeO2 structure has been prepared from isostructural NaYS2 by ion-exchange in a molten LiC1/KC1 mixture at a relatively low temperature as compared to previous syntheses using high- temperature solid state reactions. The X-ray powder diffraction data from alpha- naFeO2-type LiYS2 are reported in this paper. This ion-exchange can be completely reversed to form NaYS2 from LiYS2 using a molten NaI/KI mixture. Keywords: Ternary yttrium sulfides, Low-temperature synthesis, Inorganic chemistry, Molten salt ion exchange.
