Abstract
The Pr-doped γ-Ce2S3 red pigment was prepared by a hydrothermal combine sulfurize process. CeCl3·7H2O, Pr6O11, and CS2 were used as cerium source, dopant source, and sulfur source, respectively. Pr-doped CeO2 precursor was prepared at 180 °C with hydrothermal method, followed by sulfurize treatment 150 min at 900 °C. The effect of doped proportion, sulfurize condition to phase composition of red pigment was observed. Furthermore, the thermal stabilities and chromaticity of as-prepared pigment were investigated. Results of calcinations in the air and color measure indicated that Pr-doping enhances the resistant temperature for oxidization of pigment. A red color (L* = 25.58, a* = 29.47, b* = 17.27) was still remained after heated at 470 °C in the air.
