摘要：
In the 625-740 K temperature range on ceramic composition for 89 mol.% ZrO2 + 10 mol. % Sc2O3 + 1 mol. % CeO2 the jump in ionic conductivity was experimentally detected by a factor of ten with temperature increase. Disconnectedness of indicated anomaly with polymorphic transformation was established by method of X-ray spectral analysis. Discovered effect has the orientation character due to the synchronous ordering of grains for T >= 500 K.
