| Abstract: | Due to the incomplete coating of Fe2O3/SiO2 pigment, the color of the pigment turns black and dark over 800 ℃. In this paper, the Fe2O3/SiO2 coated pigments were prepared by sol-gel method, and then the effects of catalyst concentration, reaction temperature, mass ratio of silicon/iron and other factors on the coloration of pigments were investigated. On this basis, the coloration of the Fe2O3/SiO2 coated pigments were studied by doping with zinc ions. The results show that the proper condition of synthetic reaction is the catalyst (ammonia) concentration 0.75 mol/L, the reaction temperature 40 ℃, the silicon/iron mass ratio m(SiO2)/m(Fe2O3)=0.20, iron/zinc molar ratio n(Fe)/n(Zn)=4. The heat resistance of the Fe2O3/SiO2 coated pigments doped with zinc ions is significantly improved, and the sample shows a bright orange red tone after 850 ℃ calcination. |
