Phase changes on the surface resulting from low‐temperature annealing of yttria‐doped tetragonal ZrO2 polycrystals under controlled humidity conditions were investigated at 0.1 to 7350 Pa of water vapor pressure and 100° to 600°C for 1 to 50 h. The tetragonal‐to‐monoclinic phase transformation was greatly accelerated by increasing water vapor pressure; the transformation rate was first order with respect to the concentration of tetragonal ZrO2 on the surface of the sample.
