Abstract

To improve low mechanical properties of cubic zirconia, Al₂O₃ has been dispersed to Yb₂O₃ stabilized ZrO₂ (YbSZ). YbSZ/Al₂O₃ nanocomposite powders were prepared by solution chemistry route, and sintered bodies were fabricated by pressureless sintering. Obtained composites have finer matrix grains with increasing Al₂O₃ addition. The fracture strength of composites was remarkably increased due to the refinement of YbSZ matrix grain size. Ionic conductivity of composite at high temperatures was almost the same value of the monolithic YBSZ ceramic.
