The preparation of ternary rare earth sulfides of Ln3−xEuxS4 (Ln = Ce, Pr, and Nd) ceramics was investigated, and the effect of Eu substitution on Ln3−xEuxS4 ceramics was also studied. Ln3−xEuxS4 powders were synthesized by the sulfurization of their oxide powders using carbon disulfide gas. Ln3−xEuxS4 ceramics were sintered by pressure-less sintering method. All pressureless sintered...
The effect of Eu-substitution on the density and thermoelectric properties of ternary sulfide Ce 3–x Eu x S 4 (0≤x≤0.8) compacts was investigated. Ce 3–x Eu x S 4 powders were prepared via the sulfurization of the oxide using CS 2 gas at 1473 K. The pressureless sintered Ce 3–x Eu x S 4 compacts in the atmosphere were...
