Summary

The objective of this work was to obtain ceramic pigments starting from Zn<Subscript>2</Subscript>TiO<Subscript>4</Subscript> and containing chromophore ions (Co, Ni and Mn in 1-20 mol&percnt;), using the polymeric precursor method. Zn<Subscript>2</Subscript>TiO<Subscript>4</Subscript> displays an inverse spinel structure and can accommodate different chromophores in its lattice. The characterization was carried out by means of TG, DTA and XRD. From the TG curves, it can be stated that the pigments are stable above 600&deg;C. X-ray diffraction patterns of the materials containing Co are single phase, whereas the addition of Ni and Mn leads to second phases from 1 and 20&percnt; of substitution, respectively.
