Induced p‐ type semiconductivity in yttria‐stabilized zirconia
Journal of The American Ceramic Society, 2019 8 mol% yttria-stabilized zirconia (8YSZ) ceramic is an oxide ion conductor at atmospheric pressure but shows the onset of p-type semiconduction, in addition to the preexisting oxide ion conduction, on application of a dc bias in the range 4-66 Vcm-1 and ...

Competing Mechanisms between Dislocation and Phase Transformation in Plastic Deformation of Single Crystalline Yttria-Stabilized Tetragonal Zirconia Nanopillars [PDF]
Acta Materialia 120 (2016) 337-347, 2016 Molecular dynamics (MD) is employed to investigate the plastic deformation mechanisms of single crystalline yttria-stabilized tetragonal zirconia (YSTZ) nanopillars under uniaxial compression. Simulation results show that the nanoscale plastic deformation of YSTZ is strongly dependent on the crystallographic orientation of zirconia nanopillars. For the

Compatibility analyses of BICUVOX.10 as a cathode in yttria-stabilized zirconia electrolytes for usage in solid oxide fuel cells [PDF]
Materials Research, 2014 Copper-substituted bismuth vanadate has been considered a promising material for composite cathodes in SOFC. However, high reactivity of BICUVOX.10 towards the electrolytes still has been its greatest shortcoming.

Atomic force microscopy study of the surface degradation mechanisms of zirconia based ceramics [PDF]
28th International Conference on Advanced Ceramics and Composites
B: Ceramic Engineering and Science Proceedings (2008), 2018 Atomic force microscopy (AFM) can be used to characterise several aspects of the surface degradation and reinforcement mechanisms of zirconia based ceramics, such as crack propagation, martensitic relief formation, grains pull-out and transformation toughening.

Percolative Mechanism of Aging in Zirconia-Containing Ceramics for Medical Applications [PDF]
Advanced Materials, Volume 15, Issue 6, March, 2003, Pages 507-511, 2018 Recently, several episodes of fracture of zirconia ceramic femoral heads of total hip prostheses have alarmed the medical and scientific community regarding aging problems in zirconia prostheses. Such fractures cause immediate local tissue reactions, which require urgent medical intervention to prevent further complications.

Change in Conductivity of Yttria Stabilized Zirconia
Journal of the Japan Society of Powder and Powder Metallurgy, 2003 The change in conductivity of 8 mol% and 10 mol% yttria stabilized zirconia (8YSZ and 10YSZ, respectively) were measured during continuous current loading at 1000°C. The conductivity of 8YSZ gradually degraded with holding time in the test and it decreased to about 65% of the initial value after annealing for 1500h.

A critical comparison of methods for the determination of the ageing sensitivity in biomedical grade yttria stabilized zirconia [PDF]
Journal of Biomedical Materials Research 72(2), 239-245 (2005), 2017 Since the recent failure events of two particular series of zirconia femoral heads for total hip replacement prosthesis, a large decrease in the use of zirconia ceramics for orthopaedic implants has been observed. In spite of the biomedical success of this material during the last ten years, this was required for safety reasons, until the cause of the ...
