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 1000؛C 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. Prog. Color Colorants Coat. 2(2009), 45-51.
