15 Ιουν 2022 · Y 2 O 3 doped ZrO 2 (YSZ) ceramic material is used to protect alloy components worked in high-temperature. But its phase transformation between tetragonal phase and monoclinic phase...
1 Οκτ 2021 · For this purpose, a simple but effective methodology for comparing the transport behavior was proposed in this study, which involves high-temperature interactions between YbYSZ ceramic powders and CMAS melts.
Thus, it is concluded that for the MCZ ceramic composite sintered at a temperature of 1450 °C, a diametrical linear contraction of 24% is quite achievable for high-purity MgO (96%) and CaZrO 3 (99%) powders. Lastly, the measured YSZ diametrical linear contraction was 27.4%.
