Water-based ink-jet ink based on nano Ni and Sb doped TiO2 prepared for printing on ceramics

This study reports a simple approach to prepare a nano-TiO2-Sb-Ni yellow ink-jet ink. Yellow pigments, in terms of their morphology and color appearance, were synthesized by changing Ni/Sb molar ratios and calcination temperatures. Moreover, the particle size of optimal nano-TiO2-Sb-Ni pigment controlled by CTAB and PVP in a co-precipitation process. TGA, spectrophotometry, and XRD were used to characterize the prepared nano-TiO2-Sb-Ni pigments. SEM and TEM were used to investigate the morphology and size of the prepared nano-pigments, respectively. Finally, the synthesized spherical nano-pigment had an average diameter of 65 nm was well dispersed in water. A general ink-jet printer printed the stable, homogenous nano-ceramic ink. Ultimately, the more yellow appearance could be obtained through increasing the number of printing runs. [GRAPHICS] .

Automated summary

This study presents a simple method to prepare nano-TiO2-Sb-Ni yellow ink-jet ink by adjusting Ni/Sb molar ratios and calcination temperatures to synthesize yellow pigments with different morphology and color appearance. The particle size of the optimal nano-TiO2-Sb-Ni pigment was controlled by CTAB and PVP during a co-precipitation process. Characterization techniques such as TGA, spectrophotometry, XRD, SEM, and TEM were utilized to analyze the prepared nano-TiO2-Sb-Ni pigments, revealing a well-dispersed spherical pigment with an average diameter of 65 nm. Ink-jet printing with this nano-ceramic ink produced stable and homogenous results, where a more yellow appearance could be achieved by increasing the number of printing runs.
