ABSTRACT

Ceramic ink-jet printing technology in art tiles, decorated tablewares and other porcelain products has manyadvantages of fast and precision printing of various images with high efficiency and low cost. For the application to ink-jetprinting, ceramic ink requires a stable dispersibility with nano-sized pigments. In this paper, characteristics of pink-red aqueousceramic ink for ink-jet printing was demonstrated. CaCr0.1Sn0.8SiO5 pigment was synthesized using solid state reaction anddeagglomerated using attrition milling. The aqueous ceramic ink contains 10 wt% of the obtained CaCr0.1Sn0.8SiO5 nanopigmentwith 0.4 wt% of sodium dodecyl sulfate (SDS) as a dispersion agent. Viscosity of CaCr0.1Sn0.8SiO5 aqueousceramic ink was adjusted using 0.18 wt% of polyvinyl alcohol (PVA) for a suitable jetting from the nozzle. The preparedpink-red ceramic ink showed a good jetting property with formation of a single sphere-shaped droplet after 180 μs withouta tail and satellite droplet.
