Preparation and colour properties of Ce1-xTbxO2 pigments

Abstract

New inorganic pigments based on CeO2 were synthesized as high-temperature environment-friendly inorganic pigments. This work is focused on mixed oxides based on ceria which are doped with rare earth elements. The pigments were prepared in the series with increasing content of terbium. Their colour properties were investigated depending on content of terbium and temperature of calcination. The pigments of Ce1-xTbxO2 were applied into organic matrix and ceramic glaze. The pigments were evaluated from the standpoint of their structure, colour and particle sizes.
