Abstract
ⶠCoxMg1âxAl2O4 nano-ceramic powders (0.00 â¤Â x â¤Â 0.10) as blue ceramic pigments were prepared successfully by the low temperature combustion synthesis (LCS) method. ⶠThe characterization of nano refractory pigments was studied using different tools such as, FTIR, UV-visible, diffuse reflectance spectroscopy (DRS), different techniques of thermal analysis (TG-DTG/DTA), X-ray diffraction (XRD) and transmission electron microscopy (TEM). ⶠThe calcination temperature in the range of 500-1200 °C gives nano pigments with particle sizes in the range of 3.1-37.69 nm using oxalyldihydrazide as fuel. ⶠThe particle sizes increased as sintering of samples at different calcination temperatures. ⶠThe results show that the blue color intensity depends directly on the amount of cobalt(II) ion, calcination temperature and time.
