Rare-earth sulfides Ln 2 S 3 (Ln = Gd and Tb) were prepared by reacting their oxides with CS 2 gas at 1248 K. The synthetic powders were then consolidated by pressure-assisted sintering at 1423–1873 K. X-ray analysis showed that all the samples con

Although the reaction of Ln2O3 (where Ln = La and Sm) powders with CS2 gas is a widely used method for preparing Ln2S3, the synthetic powders contain the impurities of oxygen and carbon. The behavior of these impurities in the sintering of Ln2S3 was

In the synthesis of La2S3 via the sulfurization of La2O3 powder using CS2 gas, La2O2S was formed in the initial stage of reaction, and single-phase β-La2S3 were finally formed for a shorter period of time at higher temperature. For long sulfurizatio
