抄録	Y₂O₃ stabilized ZrO₂ (YSZ) whose equivalent spherical diameter was 77nm was used as nanoparticles, and YSZ/ethanol colloidal dispersion with a volume fraction of 30vol% was prepared using poly(ethylenimine) (PEI) as dispersant. Then, colloidal gelation was induced by adding a small amount of nonadsorbed polymer, poly (vinyl butyral) (PVB) into the colloidal dispersion. The yield stress of the colloidal dispersion increased remarkably when PVB was added at 1mass%-powder or more. The two dimensional colloidal patterns of YSZ were directly formed by extruding the colloidal gel through a micro-nozzle.
