Özet

Pigments based on CeO2 structure are known to give various pink-orange and red brown colour in ceramic glazes. This type of pigments is prepared by high temperature calcination Of CeO2 and Pr6O11 with admixed rare-earth elements such as lanthanum oxide (La2O3) and neodymium oxide (Nd2O3). In this study, the use of enriched Eskisehir Kizilcaoren region (Turkey) rare-earth oxides containing CeO2, La2O3 and Nd2O3 to synthesis CeO2-PrO2 pigments was investigated. The resulting pigments were characterised using X-ray diffraction (XRD) and were used in double firing glazes. The colour obtained after glazing was defined as L*a*b* parameters by using UV-Vis Spectrophotometer and the results were compared to pigments obtained by using pure oxides.
