Study of nano and micron structure control of the materials by novel-free ink-jet printing

Abstract

Optimization of slurry for nozzle-free ink-jet forming was investigated. 10mass% aqueous slurry of colloidal silica was prepared, and the effect of the slurry characters on the droplet formation process and the printed characters was examined. Surface tension and apparent viscosity of the slurries had the influence on the droplet formation and the printed dot diameter, and the dot diameter decreased as the viscosity increases. Using the slurry with the phosphor powder (mean particle size: 1.8μm), the clear pattern was obtained by nozzle-free ink-jet forming.
