“…Moreover, YSZ exhibits a very high radiation resistance, suggesting potential use as an IMF. This radiation resistance has been demonstrated in a series of experimental studies where the irradiation environment has been simulated with external ion beams [5][6][7][8][9][10][11][12] or also via computational approaches. [13][14][15] All works put forward that YSZ maintains its structural integrity up to very high irradiation levels ($100 displacements per atom, dpa).…”

High-temperature stability of ion-implanted zirconia and spinel J. Appl. Phys. 97, 113509 (2005) ) and at five temperatures: 80, 300, 573, 773, and 1073 K. Irradiated samples have been characterized by Rutherford backscattering spectroscopy in channeling mode, X-ray diffraction and transmission electron microscopy techniques in order to determine the disordering kinetics. All experimental results show that, whatever is the irradiation temperature, the damage build-up follows a multi-step process. In addition, the disorder level at high fluence is very similar for all temperatures. Thus, no enhanced dynamic annealing process is observed. On the other hand, transitions in the damage accumulation process occur earlier in fluence with increasing temperature. It is shown that temperature as low as 573 K is sufficient to accelerate the disordering process in ion-irradiated YSZ. V C 2014 AIP Publishing LLC. [http://dx

“…Several experiments on target fuels based on YSZ have shown the remarkable radiation resistance of this material. Actually, YSZ cannot be amorphized either by nuclear collisions or electronic excitations after irradiation with heavy ions: a polygonized structure is produced in both cases [7]. However, it is of utmost importance to sort out the respective effects of ballistic and ionization processes, in order to study the defect production by neutroninduced recoils (or α-recoils) and fission fragments.…”

“…We have previously done an extensive study on point defect production in YSZ single crystals (for 9.5 mol% yttria) by charged particle and X-ray irradiations using electron paramagnetic resonance (EPR) spectroscopy, optical absorption (OA) spectroscopy and thermo-stimulated luminescence (TSL) spectroscopy [7][8][9][10][11][12][13][14]. Two different paramagnetic electron centres are produced by electron and ion irradiations.…”

International audienceYttria-stabilized zirconia (YSZ) single crystals (for 9.5 and 18 mol% yttria)were irradiated at room temperature (RT) by X-rays (W white spectrum) and2.5-MeV electrons. The growth curves of the so-called T-centre (for trigonalcentre, i.e. Zr3+ sitting in a trigonal symmetry site) were studied as a functionof absorbed dose, or irradiation time, by UV–visible optical absorption (OA)spectroscopy and X-band electron paramagnetic resonance spectroscopy. Thedefect concentration at saturation and the production rate are increased by afactor around two for 18 mol% yttria with respect to 9.5 mol%. Defect decaywas then followed after irradiation by OA spectroscopy as a function ofageing time at RT. Growth and decay curves of the T-centre are modelled onthe basis of rate equations of charge-exchange reactions with the zirconiumlattice ions. Increase in yttrium content is thought to decrease hole trappingon Zr3+ ions, thereby enhancing T-centre formation

“…Previous ion-irradiation studies [1] have shown that YSZ cannot be amorphized in severe radiation environment, and it is, therefore, considered to be one of the potential matrices to use in extreme environments such as diluent of inert matrix fuels (IMF) and solid oxide fuel cells (SOFC) [2] . Moreover, along with CeO2 [3,4], as it is isostructural with UO2, ThO2, and PuO2, YSZ has also been used as a surrogate material for evaluating the performance of nuclear fuel and inert matrices in adversely high radiation environment.…”

Yttria stabilized cubic zirconia (YSZ) is one of the potential matrices to be used in hostile radiation environment. In the present study, the evolution of dislocation loops in sintered YSZ specimens was investigated in situ in high voltage electron microscopes under irradiation with high energy electrons as functions of electron energy from 1.25 to 3.0 MeV and irradiation temperature from 300 to 773 K. In situ microstructure observation reveals that under 1.25 MeV electron irradiation at 300 to 673 K, no dislocation loops were formed up to a fluence of 4.5×10 26 m -2. Under irradiation with 2.0 and 3.0 MeV electrons, the microstructure evolution was strongly dependent on electron energy and irradiation temperature, resulting the formation of perfect dislocation loops and/or oxygen-type dislocation loops. Results reveal an importance of the ratio of displacement damage rate between oxygen sublattice and cation sublattice, and their mobility on the nucleation-and-growth of defects in YSZ.
