What is Zirconium Oxide used for? | Luxfer MEL Technologies

Medical products. Zirconium oxide can be used as a radiopacifier in surgical cements due to its low solubility and biocompatability. Dental implants can also be manufactured from Zirconium Oxide by carefully controling the level of yttria added to fine tune mechanical strength vs. optical properties.

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
