Abstract: (4074 Views)
Black pigment with micron size has been used for ages in ceramic industry. Recently, black submicron pigments have attracted great interest in ceramic industry due to their particle size. This pigment has been distinguished for preparing of ceramic ink suitable for ink-jet technology. In this research, black sub-micron pigments were synthesized by the combustion method based on cobalt chromite (MnxCoCr2-xO4) with different amount of manganese. The all samples were calcinated at 1000 ◦C. Samples were characterized by X-ray diffraction, colorimetry, scanning electron microscopy. The results showed that the optimum amount of manganese was 0.9%mol. In the presence of Manganese as dopant the color of pigment will change from to black. The morphology of the particles indicating that particles were synthesized in sun-micron range mainly 200-400 nm by combustion method.
