Ink-jet printing technology has been attractive due to its capability of direct and fine printing onto various substrates. Recent studies have been focused on the expansion of the ink-jet printing application from the purpose of general consumer use and design companies to prototype production of precision parts and parts manufacturing. The use of ink-jet printing technology with ceramic pigment which is a highly stable coloring agent to decorate porcelain products, glass, plastics also has many advantages. There is no direct contact point between the printer and the substrates to be printed, thus the printing process is fast and can be adaptable to various kinds of objects. For the application of ink-jet printing technology to ceramic product decoration, the ink containing highly dispersed inorganic nano-pigments is required. Here, we report the synthesis and characterization of ceramic nano-pigment with thermal and glaze stability for ink-jet printing. Inorganic pigments were synthesized by solid state reaction. Then pigments were grinded using the attrition milling with constant speed of 800 rpm and ball to powder weight ratio was 100:1. The prepared nano-pigments were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), particle size analyzer (PSA) and CIE L*a*b*. Ceramic ink based on the obtained nano-pigment was prepared by the dissolving pigment particles in the solution with the appropriate viscosity and surface tension for ink-jet printing. The ink solution contains 15 wt% of nano-pigment and CTAB(Cetyltrimethyl ammonium bromide) and SDS(Sodium dodecyl sulfate) as a dispersive agent. The prepared ceramic ink was stably jetted with the formation of sphere-shaped droplet from ink-jet printer.
