"This study deals with rutile pigments of type Ti1-3xCrxM2xO2 (where M = Sb, W and x = 0, 0.05, 0.10, 0.20, 0.30, 0.50) prepared by solid state reaction. Chromium is the chromophore (coloring ion); antimony and tungsten are added for achieving electroneutrality. The effect of doping elements (M = Sb, W), calcination temperature (850, 950, 1050, 1150 degrees C) and composition (x = 0, 0.05, 0.10, 0.20, 0.30, 0.50) on color properties, particle size and electrokinetic (zeta) potential was observed. The optimal conditions for synthesis of these rutile pigments are Sb2O3 as raw material, calcination temperature 1050 degrees C and composition x = 0.20 (Ti0.4Cr0.2Sb0.4O2). This orange-green pigment has high stable dispersion (zeta = -43.81 mV) and good color properties (chroma C = 39.50). However, brightly orange pigment Ti0.85Cr0.05W0.10O2 (x = 0.05) synthesized at temperature 1050 degrees C gives %22the finest%22 color with higher chroma (C = 49.48), but less stable dispersion (zeta = -37.32 mV). In light of phase composition, the optimal calcination temperature is 1150 degrees C."@en . "1895-1066" . . . "The Study of Rutile Pigments Ti1-3xCrxM2xO2"@en . . "\u010Cech, Jan" .
