Abstract
New nano-blue ceramic pigments of CoxMg1−xAl2O4 (0≤x≤0.1) have been prepared by coprecipitate–
combustion as a hybrid method using urea as a fuel at 500 ◦C in open furnace in air
atmosphere. The structure of pigment is assigned based on TGA/DTA/DrTGA analyses, X-ray diffraction
(XRD) and transmission electron microscopy (TEM). Also, electronic spectra, infrared (IR) and diffuse
reflectance spectroscopy (DRS) using CIE L*a*b* parameter measurement techniques were used. The
results revealed that the nano-particle size of pigments were obtained in the range 30–38nm as well as
the varying colors and particle size as a result of different calcinations temperatures within the range of
500–1200 ◦C for 2 h.
