摘要：Zn0.9Co0.1O ceramic pigments were synthesized using simple high energy milling method. Zinc and cobalt oxides were used as starting materials. Products were investigated using simultaneous thermal analysis and fourier transformation infrared. Pigments were characterized using X-ray diffraction, diffuse reflectance and Scanning Electron Microscopy. The results showed the effect of calcination temperature on Co solubility and crystallite size. Nano-crystalline Zn0.9Co0.1O pure solid solution synthesized at different temperatures consist of 300-500 nm semispherical particles. Crystallite size of Zn0.9Co0.1O calcinated at 1000ºC was about 100 nm. A broad reflectance band around 540 nm (green region) for all powders indicating the appearance of deep green pigment was observed. Furthermore, elevation of calcination temperature caused the increase of color saturation.
