Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance is a non-flammable inorganic solid, and as a consequence, it cannot be ignited.
The calcium metal ion in calcium difluoride is already present in the highest possible oxidation state. Fluoride cannot be oxidised by oxygen because fluorine is a more electronegative element than oxyen. As a consequence, it is clear that calcium difluoride cannot react with the oxygen in air, and hence, is not combustible.
In addition, based on the experience in handling and storage, the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence the classification procedure does not need to be applied.
Key value for chemical safety assessment
Additional information
The substance is a non-flammable inorganic solid. Based on a theoretical consideration of its chemical structure, autoflammability is not predicted.
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.
