Structural studies of zirconia and yttria doped zirconia for analysing it phase stabilization criteria

Growth of zirconia and yttria-stabilized zirconia nanorod arrays assisted by phase transition

Well-aligned, densely distributed ZrO2 nanorod arrays were fabricated using a non-catalytic, templatefree metal–organic chemical vapour deposition process at a reaction temperature of 1000 C. The reaction temperature was found to play a key role in product morphology, with particle thin films obtained at 550 C and nanorod arrays produced at 1000 C. Increasing the reaction temperature led to the...

Computational Modelling Study of Yttria-stabilized Zirconia

WEAR REESISTANCE OF NANOSTRUCTURED AND CONVENTIONAL YTTRIA-STABILIZED ZIRCONIA COATINGS

Partially stabilized zirconia (PSZ) has been proven to be an excellent candidate as a thermal barrier coating (TBe) for hot sections in, for instance, heat or internal combustion engines and gas turbine parts. The main functions of these coatings are reducing heat losses, reducing fuel consumption, increasing efficiency, and extending durability and life. One of the main problems involved is we...

Molecular dynamics simulations of yttria-stabilized zirconia

Oxygen diffusion in the oxygen ionic conductor yttria-stabilized zirconia is investigated by means of the molecular dynamics simulation technique. Oxygen ions migrate by means of a discrete hopping process, mainly between neighbouring tetrahedral sites. Diffusion appears to occur in a short time and a long time regime. Only when the oxygen ions have moved over distances much larger than the cha...

Transparent nanocrystalline yttria-stabilized-zirconia calvarium prosthesis.

UNLABELLED Laser-based diagnostics and therapeutics show promise for many neurological disorders. However, the poor transparency of cranial bone (calvaria) limits the spatial resolution and interaction depth that can be achieved, thus constraining opportunity in this regard. Herein, we report preliminary results from efforts seeking to address this limitation through use of novel transparent cr...
