Abstract: (1969 Views)
In this paper cobalt aluminate (CoAl2O4) has been synthesized by ceramic method using CoCl2 and Al2O3. The calcination process for pigment has been performed at 1200ᵒC. The Nano-pigment has been dispersed in a solvent by a milling system and an ink is obtained. The ink is used for printing on the ceramic surface. The Nano pigments have been analyzed by XRD, SEM and CIE colorimetric system. XRD spectrum shows the pigments is composed of two crystal structure containing CoAl2O4 and Al2O3. SEM images show the average particle size for pigment is about 237 nm and the average particle size for pigments on the printed ceramic is about 115 nm. Color values of samples indicate the blue values of49.5 and 34.37 for nano pigment powder and printed respectively.
