Description of key information

The substance is a non-flammable inorganic solid. It cannot react with oxygen, and thus 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.

Furthermore, experience in handling confirms that the substance is stable in contact with water and in contact with air for prolonged periods of time.
