The effect of low-temperature aging of ceramics Zr0.97Y0.03O2 (Y-TZP) and Zr0.98Y0.02O2 (Yb-TZP) by the methods of the high-grade diffraction analysis and atomic force microckopy is studied. Formation of the phase… Click to show full abstract

The effect of low-temperature aging of ceramics Zr0.97Y0.03O2 (Y-TZP) and Zr0.98Y0.02O2 (Yb-TZP) by the methods of the high-grade diffraction analysis and atomic force microckopy is studied. Formation of the phase M-ZrO2 in ceramic (Y-TZP) in a large quantity after hydrothermal impact in subsurface layers of ceramic samples is shown. A positive effect of the stabilizing cation Yb+3 on the phase composition stability and strength properties of ceramic based on T-ZrO2 is registered. Adaptation of the structural ceramic based on T-ZrO2 according to medical requirements is the aim of this study.
