Abstract: (3002 Views)
CoAl2O4 nano pigments were fabricated using cobalt chloride and aluminum oxide as a ceramic blue pigment by co-precipitation . The product was calcinated at 1200°C. Three samples were made under different conditions and homogenized in a solvent using a milling system to prepare an ink. It has been printed on a ceramic by silk screen method. The powder was characterized by XRD, SEM and colorimetric tests to identify the structure, color parameters and microstructure. The results of XRD experiments show that CoAl2O4 nanoparticles were formed in all three samples. The results of the particle size distribution and SEM images of the manufactured powders show that with increasing milling time, the average particle size will decrease from 413 nm to 181 nm. Also, the printed ceramics were characterized by SEM and colorimetric tests.
