It was determined that the mean grain boundary radius of curvaturer¯ b in 3 mol% yttria‐stabilized zirconia isothermally annealed without and with a DC electric fieldE 0 ∗ = 18 V/cm was uniquely proportional to the mean linear intercept grain sized¯ , the proportionality constant α = 3/2 being in accord with the Rios‐Fonseca stereological model.
