"Synthesis of rutile pigments is based on solid state reaction and on Hedvall effect, i.e., phase transformation from anatase to rutile. Therefore, it is important to know the thermal behavior of these compounds (the temperature of this change). The goal was to prepare rutile pigments of type Ti1-3xCrxNb2xO2+x/2 by conventional solid state method from titanium dioxide TiO2 (AV-01, anatase), to determine an influence of composition (x = 0, 0.05, 0.10, 0.20, 0.30, 0.50) and calcination temperature (850; 900; 950; 1,000; 1,050; 1,100; 1,150 degrees C) on color properties of these compounds and to analyze other starting compounds of titanium (hydrated anatase paste TiO2.nH2O, titanyl sulfate dihydrate TiOSO4.2H2O (VKR 611), hydrated sodium titanium oxide paste Na2Ti4O9.nH2O) and their reaction mixtures for x = 0.05 by simultaneous TG-DTA analysis. According to the highest chroma C of color, the optimal conditions for synthesis of these pigments are concentration x = 0.05 and calcination temperature 1,050 degrees C and higher. It was observed that initial temperature 760-830 degrees C is needful for a formation of rutile structure. This temperature is the lowest for hydrated Na2Ti4O9 paste (760 degrees C) and similar for other starting compounds of titanium."@en . . "Ve\u010De\u0159a, Jan" . . . "113" . .
