Abstract: Preparation of Bi₂O₃-ZnO-Nb₂O₅(BZN) ceramic ink for Ink-Jet printing was studied with an aqueous, multifunctional organic solvent-sokalan PM70. The effects of different content of PM70 and the solid content BZN powder on the stability and viscosity of suspension liquid were discussed, and rather stable ink with high solid content was obtained. A planar capacitor was printed successfully with the prepared ink by the iP-210 Personal Plotter controlled by MD-E-201H. The influence of controlling parameters on the Ink-Jet printing was also dealt with. The thickness distribution of printed images was measured by Rodenstock RM600S. The experiment indicates that when the content of PM70 is 3.2wt％, the stability of ceramic ink is much more stable with the highest solid content of 48.8wt％. A better practical printing result will be obtained in the condition that drive voltage is 10V, the pulse width is 1.5 and the pulse period is about 800μ s.
