Abstrakt:	Abstract: Inorganic pigments of type YFex (M) 1-xO3, where M = In or Ga and x = 1 or 0.95, were synthesized by mechanical activation in liquid medium (H2O + C2H6O) and successive two-step heating in the range 900 - 1300 °C. TG-DTA analysis of a mixture of starting oxides Fe2O3 and Y2O3 was performed in order to compare the thermal behavior of reagents before and after mechanical activation. YFeO3 was prepared as a standard and applied into the ceramic glaze and acrylic copolymer matrix (mass and diluted tone). Samples were characterized by XRD analysis, particle size distribution (PSD) and color measurements. The effect of substitution of 5 mol% Fe3+ for In3+or Ga3+on the changes of pigment properties was examined.
