1. A method for enhancing the fracture toughness of an yttria-stabilized zirconia ceramic material comprising:
a. applying a solution to a porous ceramic body that comprises an yttria-stabilized zirconia material stabilized by 3 mol % to 12 mol % yttria, the solution comprising
1. 10 wt % to 80 wt % of a tantalum alkoxide;
2. 20 wt % to 90 wt % of a co-solvent system comprising a first solvent and a second solvent that is different than the first solvent, and
3. 0.1 wt % to 10 wt % of a soluble polymer that is soluble in a polar solvent;
b. penetrating at least a portion of the porous ceramic body with the solution; and
c. drying and sintering the porous ceramic body.
