The adsorption behavior of Cu 2+ on 3‐mol%‐yttria‐stabilized tetragonal zirconia polycrystalline (3Y‐TZP) powder was studied. There is a window of ph values (10 < pH < 11) where adsorption may be used as a method of doping 3Y‐TZP with Cu 2+ . The maximum mole percent of the CuO additions is determined by the specific surface area of the 3Y‐TZP powder; a powder with a specific surface area of 16.1 m 2 /g is limited to about 1 mol% CuO. Compacts made from powders doped with CuO using this method exhibited an enhancement in superplasticity comparable to that observed in other studies using samples doped with CuO by attrition milling.
