| Abstract: | Scandium sulfides were synthesized from its stable oxide, Sc2O3, using CS2 gas. Suitable temperature and time for synthesis were examined experimentally using a constant flow rate of gas mixture of Ar and CS2. The high rate of evaporation from liquid CS2 enhanced formation and stoichiometry of sulfides, and eliminated impurity carbon. Most of parts in the sample were converted to Sc2S3 at 1473 K for 7.2 ks, and a transient phase of Sc2O2S was often synthesized after a prolonged time under certain oxygen and sulfur potentials. |
