Abstract

Abstract: The tetrathiotungstate crystals (NH₄)₂WS₄ and K₂WS₄ were first synthesized by the solventothermal technique by using water-alcohol as solvent at low temperature, and characterized by SEM, XRD, ED techniques. Results show that their crystal phases are pure and their shapes are good. The synthesis procedure is simple and high yield, produces less pollution.

Key words: solventothermal synthesis, tetrathiotungstates, XRD, SEM and ED characterization
