Non-equilibrium Oxidation States of Zirconium during Early …

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

Zirconium Oxide

Zirconium oxide and compounds containing zirconium are increasingly being recognized as useful catalytic materials. In particular, zirconia (ZrO 2 ) is an important support material for catalysis, due to its acid–base properties [ 1 ], and also because it is chemically more stable than the classic materials such γ-alumina and silica [ 2 ].

The Influence of Oxide Color on the Surface Characteristics of

Oxidized zirconium alloys can appear as black, white and all gray shades depending on the heat treatment process. The black color results from a high amount of oxygen vacancies in non-stoichiometric zirconia (ZrO2−x) that effectively reduces the band gap of the material. In this work we compare the surface properties of black and white …
