Dysprosium Sulfide

Dysprosium sulfide is reddish brown crystal powder, which is a kind of rare earth metal sulfide thermoelectric material. Its owns very high Seebeck coefficient and conductivity. After hot pressing, dysprosium trisulphide change from α-phase to γ-phase cubic crystal. Doping lanthanum and cerium could reduce the sintering temperature and increase the stability of dysprosium trisulphide. At low temperature, the thermoelectric property of Dy₂S₃ is bad. At temperature higher than 500℃, Dy₂S₃ shows relatively good thermoelectric property. The thermoelectric figure of merit (ZT value) of Dy₂S₃ is relatively high at high temperature.
