Аннотация
The strength, the fracture toughness, the thermal shock resistance, and the electrical conductivity of a ceramic Na–β"-Al2O3 solid electrolyte modified by t-ZrO2 additions are studied. The influence of the reverse t-ZrO2 → m-ZrO2 transformation on the mechanical and functional properties of the ceramics is discussed. The ZrO2 addition concentration is found to affect the sodium-ion conductivity of the solid electrolyte and its activation energy. The degree of defect accumulation in the ceramics modified by 8.5 wt % t-ZrO2 is shown to decrease during a thermal shock.
