Zirconia was prepared at low temperatures (<450°C) using single several source precursors based on zirconium carboxylates where the R groups were systematically varied. The combination of density functional theory (DFT) calculations and extensive characterization of the precursors (i.e., X-ray diffraction, thermal gravimetric …
dynamic data of zirconium, it is needed to make the behavior of colloidal species clear. In the present study, the influence of the formation of pol-ynuclear and colloidal species on the apparent solubility was investigated by an ''undersaturation'' method. The zirconium oxide (ZrO 2) and zirconium hydroxide (Zr(OH) 4) were used
This chapter presents a comprehensive review of the creep technique used for the study of defect structure and diffusion in metal oxides, both single crystals and ceramics. At high temperatures, the creep rate is proportional to the diffusion coefficient of the slowest species in solid compounds, whatever deformation mechanisms are present …

Raman mapping of sectioned zirconium cladding oxides was performed to analyze different spectral features before and after breakaway, as well as between zirconium and its alloys Zr-2.65Nb, Zry-3, and Zry-4. Oxide phase composition, or percent tetragonality, was defined to compare tetragonal to monoclinic zirconia.
Oxidized zirconium implants (Oxinium; Smith and Nephew, Memphis, TN) were developed to potentially improve the longevity of total hip (THA) and total knee ... This transformation is a result of oxygen diffusion into the zirconium when heated, thus forming a zirconium oxide (zirconia) ceramic layer. This material has a hardness greater than that ...
The Speedmaster Dark Side of the Moon is crafted from a single block of black zirconium oxide ceramic. The dial and pushers are also made of this material. Omega decided to put a soft nylon strap on the Dark Side of the Moon, with a simple but elegant black ceramic buckle as well. The fact that Omega used the Speedmaster Co …

Thermal atomic layer etching (ALE) can be achieved using sequential, self-limiting fluorination and ligand-exchange reactions. Previous studies have demonstrated thermal ALE of amorphous HfO 2 and ZrO 2 ALD films. This study explored the differences between thermal ALE of amorphous and polycrystalline films of hafnium oxide, …
Results. In the experimental group receiving 400 ppm Zirconium oxide nanoparticles, the number of Spermatogonia cells (p ≤ 0.01), Spermatocytes (p ≤ 0.01), Spermatids (p ≤ 0.001), and sertoli and Leydig cells (p ≤ 0.05) showed a significant decrease compared to the control group. Serum testosterone concentration did not change …
The crystal world of pure zirconium oxide is diverse. Zirconium oxide is a polymorphic material, just like its basic element zirconium (Sect. 6.3 in Chap. 6 ). Depending on the temperature, the oxide occurs in three different crystal lattices, which differ in density and thus also in volume.

Zirconium absorbs oxygen, nitrogen, and hydrogen in astonishing amounts. At about 800 °C (1,500 °F) it combines chemically with oxygen to yield the oxide, ZrO 2.Zirconium reduces such refractory crucible materials as the oxides of magnesium, beryllium, and thorium.This strong affinity for oxygen and other gases accounts for its …

It is well known that oxygen diffuses inwards across the oxide film while cations are relatively immobile during the oxidation of Zr . 11. Therefore, the new oxide layers form at the metal/oxide interface as the oxidation progresses. Oxygen diffusion assisted by an electric field (Mott potential) governs the early stages of metal oxidation. 12-14
Thin films containing either multilayer ZrO2:Al2O3 structures or ZrO2 deposited on ZrxAlyOz buffer layers were characterized.
