The results of research on preparation of ceramic pigments with the perovskite structure, coloured by chromium ions are discussed in the paper. The Y(Al1-xCrx)O3 pigments were obtained via the solid state reaction using different mineralizers. The effect of synthesis conditions on the phase composition as well as unit cell volumes, particle size distributions and the morphology of the pigments was connected with their colour. The thermal and chemical stability of the pigments was established in industrial gres porcellanato bodies.
