Abstract
Single−phase ZnAl2O4 spinel successfully synthesized at low temperatures using rosin as an organic precursor. Co(II) ions were doped to the ZnAl2O4 spinel structure to produce Zn1-xCoxAl2O4 blue pigments (x = 0.1, 0.3, 0.5, 0.7, 0.9). The obtained powders were characterized by Thermal Analysis (TG−DSC), X−ray Diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy and CIE L*a*b* colorimetry. The TG-DSC data suggested that the calcination temperature of ZnAl2O4 spinel formation started from 900 °C. Besides, XRD results showed that the spinel structure calcinated for 4 h, at 1000 °C with 15 °C/min heating rate had good crystallinity. The intensity of blue color increased gradually with the content of Co(II). The obtained pigments which presented high thermal stability were suitable for the production of enamel.
