Ceramic Pigments Based on Doped Strontium stannates
Original language description
This study reports the development of red-shade inorganic pigments based on chromium- and terbium-doped strontium stannate. Perovskite compounds belong to group of high-temperature pigments. Powder samples were prepared by the conventional ceramic method, i.e. solid-state reaction. Pigments were characterized by X-ray diffraction analysis and thermal analysis. Powder morphology was analysed by scanning electron microscopy. The colouring mechanism seems to result from the combined contribution of octahedral Cr(III) and tetrahedral Cr(IV) species replacing Sn4+. Colorimetric parameters were evaluated by measuring the reflectance in the visible region of light, and their colouring performance was tested in an organic matrix and transparent ceramic glazes.Intense reddish brown hues were developed with optimized formulations, i.e. containing 0.1 Cr and 0.1 Tb at 1,350 A degrees C.
