Aqueous tape casting was developed to fabricate YSZ films using a cobinder. The processing parameters such as pH value, dispersant content, and binder type and content on the quality of YSZ films were investigated and optimized. The results show that at pH = ～ 9.6, the YSZ suspensions with 0.8wt% of the dispersant PAA have a good stability. The degree of pseudo-plastic and viscosity of slurry using different binders increased with the increasing of PVA content, in contrast, the degree of pseudo-plastic and viscosity decreased with the increasing of B1070 content. The density and drying shrinkage of YSZ green tape are tightly related to the different binders. The sintered density of YSZ film increased as the density of green tape increased. The green tape using PVA (30wt %) +B1070 (70wt %) cobinders was sintered at 1400℃ for 2 hours. The films of YSZ with 98.5% of theoretical density have been obtained.
