The nanocomposites of which the ZrO2 phase is stabilized with 1 mol% Y2O3 and 1–1.75 mol% Nd2O3, PECS at 1400 or 1450 °C, combine a hardness of about 13 GPa with an excellent bending strength of 1.1–1.3 GPa and a low electrical resistivity (1.6–2.2 × 10−5 Ω m). Moreover...
On the Y2O3–Ta2O5–ZrO2 phase diagram at 1500 °C, [24], apart from the tetragonal zirconia phase, formed by equal co-doping of Y2O3–Ta2O5 into ZrO2, a stable orthorhombic zirconia phase (TaZr2.75O8) also exists, when ZrO2 is doped with low level of Y2O3 and high level of Ta2O...

ZrO2材料兼具优异的力学性能和功能特性,但温度诱发的同素异构转变限制了其应用.氧化物掺杂是稳定ZrO2高温相,拓宽其应用范围的重要手段.其中,Y2O3稳定ZrO2(Y2O3-ZrO2:YSZ)最为成熟,广泛用于热障涂层,燃料电池和氧传感器等领域.为阐明Zr氧化腐蚀,热障涂层失效,燃料电池寿命等问题,需对ZrO2和YSZ的扩散生长与扩散行为进行...
The phase diagram for the system ZrO2-Y2O3 was redetermined. The extent of the fluorite-type ZrO2-YzO3 solid solution field was determined with a high-temperature X-ray furnace, precise lattice parameter measurements, and a hydrothermal technique. Long range ordering occurred at 40 mol% Y2O3 ...
