Abstract

Abstract An equilibrium isotherm on V‐S system at 900°C was determined by changing partial pressure of sulfur. Single crystals of several V 5 S 8 and V 2 S 3 compounds were grown by chemical transport. The grown crystals almost satisfied compositional relation on equilibrium isotherms between 900°C (hot zone) and lower temperatures (cold zone). Electrical conductivity of the single crystals was measured at temperatures from liquid nitrogen to 25°C. It showed metallic behavior without any significant dependence on compositional variation. Also the conductivity measurement of sintered samples for various vanadium sulfides was carried out in the compositional range from VS 1,38 (V 3 S 4 phase) to VS 1,58 (V 5 S 8 phase).
