Effect of Y2O3 addition on the phase composition and crystal growth behavior of YSZ nanocrystals prepared via coprecipitation process

Compositional and operational impacts on the thermochemical reduction of CO2 to CO by iron oxide/yttria-stabilized zirconia

“…3A by X-ray diffraction (XRD) at room temperature revealed a change in structure of the zirconia phase from monoclinic at low yttria content (below 6 mol% Y 2 O 3 ) to cubic at higher yttria contents (6 mol% Y 2 O 3 and above, see ESI, Section S5 † ). These observations agree with the literature for undoped YSZ 52 and Fe-doped YSZ. 53 For samples containing 21.2 mol% Fe, un-dissolved hematite (Fe 2 O 3 ) was observed in all samples, as expected.…”

Damping performance of YSZ coating prepared by different EB-PVD parameters

“…The boundary between particles becomes insignificant. This is because faster grain growth in the coating leads to a mixed crystal phase in the coating and blurs the grain boundaries [26,27]. It is the reason for less energy consumption and poor damping performance under the loading circumstance.…”

Temperature sensitivity and transition kinetics of uniform corrosion of zirconium alloys in superheated steam

“…As for the limiting critical value ( ), researches on YSZ laid strong evidence of the dependent relationship of the critical grain size of t-ZrO 2 particles on doping contents [ 44 ]. W. Qin et al [ 45 ] has proposed a thermodynamic model to calculate the critical size of t-ZrO 2 and its relationship with parameters.…”

“…The activation energy of grain growth kinetics for submicron-sized 3 wt%-Y 2 O 3 -stabilized YSZ (3YSZ) was not considered herein [ 42 , 47 ], since the t-ZrO 2 particles generated on zirconium alloys must be nanoparticles [ 39 ]. However, the activation energy for growth kinetics of nanoparticles fabricated by different methods were much smaller compared with [ 44 , 48 ]. But the value of oxygen diffusion in YSZ has exactly the same magnitude with in wide range of temperature [ 49 , 50 ].…”
