The pigments used in ceramic applications are of nature predominantly inorganic and they should be thermally stable, insoluble
in glazing, resistant to the chemical and physical agents' attacks. This work aimed at the synthesis by the polymeric precursor
method of ZrO2-based inorganic pigments, doped with Fe, Ni, Co, Cr and Cu cations. The fired pigments were characterized by thermogravimetry
(TG), differential thermal analysis (DTA) and X-ray diffraction (XRD). Among the metals used to zirconium-doping, the best
result was achieved with the cations Cu, which presented the monophase pigment, even as 20 mol% of dopant. Up to the temperature
of 1000C the pigments presented a good thermal stability.
