Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Zirconium dioxide is a stable inorganic metal oxide with the metal in its highest oxidation state, and therefore not sensitive to oxygen release. This is confirmed by the release of energy when zirconium is oxidized and by the limited amount of hydrogen which is consumed by pure ZrO2 at high temperature (1200K). Furthermore, experience in the day-to-day handling and use of the substance shows no oxidizing potential.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
Justification for classification or non-classification
Zirconium dioxide being a stable inorganic metal oxide is not sensitive to oxygen release. Experience in the day-to-day handling and use of the substance shows no oxidizing potential.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
