Abstract:
Pigments based on YMnO3 doped by ions of Sn with general formula YMnx(MSn)1-xO3±δ, where x =0.9; 0.5; 0.1; and M = Cu or Ni were prepared by mechanical activation and their color properties, phase purity, PSD were measured. The mineralizers were used to improve properties of these compounds. The color shade is shifting from black to dark green for (CuSn) and from black to dark brown for (NiSn). The XRD analysis showed that pigment YMn0.9(CuSn)0.1O3±δ provides single-phase perovskite structure at 1100 °C. The use of mineralizers caused increase of intensity of the crystalline phase.
