The dependence of an averaged ionic transport number and the ac conductivity on oxygen activity was determined at 500° and 600°C for Nb 2 O 5 ‐doped Pb(Zr 1‐∞ Ti ∞ )O 3 ( x =0.07, 0.10, 0.20, and 0.35). The electrical conductivity has a p ‐character and indicates a complex dependence on [Ti] and P o 2 . For P o 2 <10 ‐3 atm the electrical conductivity increases linearly with [Ti]. For oxygen activities from 1 to 10 ‐8 atm all PZT compositions showed some degree of electronic conduction.
