“…The study on the production of red ceramic pigments with high thermal stability is of great importance to the industry [16]. One way to obtain red pigments is the doping of ceria (CeO 2 ) with praseodymium (Pr 4+ ) ions, which is the method that yields a stable dye [17][18][19]. The production of ceramics pigments is focused towards obtaining high surface area pigments in the form of powder, since this feature influences the color intensities.…”

KAUST Repository M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT AbstractCeramic pigments based on cerium oxide were synthesized by self-propagating room temperature method and their color properties were assessed from the viewpoint of potential environmentally nontoxic pink pigments. Thermal stabilities of the pigments were examined at 600, 900 and 1200 ºC. According to X-ray powder diffraction and Raman spectroscopy results, all obtained pigments were single-phase solid solutions of cerium oxide, independent of the concentration of dopants. The X-ray analysis showed that the crystallites were of nanometric dimensions, as recorded and by transmission electron microscopy analysis. Color characteristics of solid solutions, which depended on concentracion erbium ions and calcination temperature, M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPTand their position in the chromaticity diagram were studied by ultraviolet-visible spectrophotometry, which confirmed potential application of environmentally friendly pigments of desired color. The color efficiency of pigments was also evaluated by colorimetric analysis.

“…From the previous thermoanalytical studies it was stated that process of reduction is represented by endothermal effect on the DTA curve. Oxidation of trivalent praseodymium ions to tetravalent ions proceeds at an exothermal process at temperatures of around 1300°C [23].…”

“…More recently, it has been shown that incorporation of praseodymium oxide into ceria-zirconia mixed oxide system yields Ce-Zr-Pr-O solid solution which exhibits high activity in soot oxidation reactions [18]. Moreover, Pr 6 O 11 is used as a sensor for environmental analysis [19], a colorant for glasses and enamels, and the high-temperature calcination products of its powder mixture with CeO 2 (Pr x Ce 1−x O 2 ) is a pigmentary material that sheds interesting color hues in ceramic glazes [20].…”
