Thermoelectric properties of Th3P4-type rare-earth sulfides Ln2S3 (Ln = Gd, Tb) prepared by reaction of their oxides with CS2 gas
Rare-earth sulfides Ln2S3 (Ln = Gd and Tb) were prepared by reacting their oxides with CS2 gas at 1248 K. The synthetic powders were then consolidated by pressure-assisted sintering at 1423-1873 K. X-ray analysis showed th
