【Abstract】 The red violet ceramic pigments doped with CeO 2 and La 2O 3 were synthesized under 1100 ℃ by precipitation method. The pigments were used in a high temperature glaze. The color, crystalline and size were characterized by color measuring, XRD and SEM analyses. The color changing mechanism of the pigments with doping CeO 2 and La 2O 3 was also discussed. The results show that the as prepared pigment can color the glaze stably at 1320 ℃. With the increase of the rare earth oxide content, a new phase of (La, Ce)(Mn, Fe, Cr)O 3 forms in the pigments, meantime, the color of the pigments changes from red brown to red violet.更多还原
