ABSTRACT

Digital ink-jet printing system has many advantages such as fast and fine printing of various images, highefficiency and low cost process. Generally digital ink-jet printing requires ceramic pigments of cyan, magenta, yellow andblack with thermal and glaze stability above 1000oC for the application of porcelain product design. In this study, pink-redcolored CaO-SnO2-Cr2O3-SiO2 pigment was synthesized using solid state reaction. The synthesis conditions of Ca(Cr,Sn)SiO5pigment such as annealing temperature, amount of mineralizer and non-stoichiometric composition were optimized. Crystalstructure and morphology of the obtained Ca(Cr,Sn)SiO5 pigment were analyzed using XRD, SEM, PSA, FT-IR and effectof Cr substitution on the pigment color was analyzed using Uv-vis. spectrophotometer and CIE L*a*b* measurement.
