Abstract

Three frits conceived for high porosity single firing tiles containing different amounts of cerium oxide and their glazes were investigated. The glazes obtained under industrial firing were studied using X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and scanning electron microscopy (SEM) with energy dispersion spectroscopy (EDS). The mechanism of the lustre effect on the surface was explained. The results indicate that the glaze presents iridescent colours on the surface, mainly associated to the formation of a very thin layer of CeO2 crystals. Moreover, the CeO2 crystals present a preferential orientation and different dimensions.
