Effect of the ZrO2-Based Solid Solution on the Low-Temperature Phase Stability of ZrO2−Y2O3−CeO2 Materials
The low-temperature phase stability of 97 mol.% ZrO2–3 mol.% Y2O3, 95 mol.% ZrO2–3 mol.% Y2O3–2 mol.% CeO2, 92.5 mol.% ZrO2–2.5 mol.% Y2O3–5 mol.% CeO2, 90 mol.% ZrO2–2 mol.% Y2O3–8 mol.% CeO2, and 88 mol.% ZrO2–12 mol.% CeO2 materials in the ZrO2–Y2O3–CeO2 system was studied. The phase stability was determined through accelerated aging in hydrothermal conditions for 7 h and 14 h. The evaluation criterion was the amount of the M-ZrO2 phase that formed in the samples when aged in hydrothermal conditions. The properties of the materials were analyzed by X-ray diffraction and electron microscopy. The T-ZrO2 → M-ZrO2 phase transformation occurred to varying degrees in all samples except for the 88 mol.% ZrO2–12 mol.% CeO2 sample after the first and second aging cycles. The smallest amount of M-ZrO2 formed in the 90 mol.% ZrO2–2 mol.% Y2O3–8 mol.% CeO2 sample. After both aging cycles, the fracture patterns for the 90 mol.% ZrO2–2 mol.% Y2O3–8 mol.% CeO2 and 88 mol.% ZrO2–12 mol.% CeO2 samples did not change significantly. With the complex stabilization of zirconia by yttria and ceria, the T-ZrO2 → M-ZrO2 phase transformation was controlled in the aging process by the number of oxygen vacancies resulting from the presence of yttria and by the stresses induced by the presence of ceria in the solid solutions. The number of oxygen vacancies decreased as ceria content in the ZrO2-based solid solutions increased, slowing down the rate of water diffusion and enhancing the low-temperature phase stability in the ZrO2–Y2O3–CeO2 materials. The effectiveness of using the 90 mol.% ZrO2–2 mol.% Y2O3–8 mol.% CeO2 and 88 mol.% ZrO2–12 mol.% CeO2 composites for the microstructural design of medical materials with increased resistance to low-temperature degradation in humid environments was shown.
