Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Reaction mass of cerium dioxide and zirconium dioxide should be considered non explosive.
Data on constituents:
Cerium dioxide: non explosive (experimental result)
Zirconium dioxide: non explosive (waiver)
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
No data on the explosive properties is available on reaction mass of cerium dioxide and zirconium dioxide. The potential for having explosive properties is thus assessed via information available on the constituents. For cerium dioxide, one GLP-compliant experimental study, scored as Klimisch 2, is available (Cerutti M., 2005) and shows no explosive properties for this substance. This data was selected as a supporting study. For zirconium dioxide this is based on a waiver statement: "Considering the chemical structure of the substance and taking Appendix 6 of UN regulation for the use of screening procedures to assess explosive properties and the ECHA Endpoint specific guidance (R.7a) into consideration, zirconium dioxide is considered not to contain any chemical groups indicating explosive properties."
Justification for classification or non-classification
Both main components in reaction mass of cerium dioxide and zirconium dioxide
do not contain any chemical groups associated with explosive properties and it is therefore concluded that the subtance is non explosive. In addition an experimental study on cerium dioxide concluded to be non-explosive. As no chemical interaction between zirconium dioxide and cerium dioxide is expected, reaction mass of cerium dioxide and zirconium dioxide is considered not to be explosive.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.
