Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Strontium oxide is not classified as highly flammable, has no pyrophoric properties and does not emit flammable gases in contact with water.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Flammability of solids
Testing of flammability is not considered to be required for metal oxides in which (i) the cation is in its highest possible oxidation state (e.g. Sr2+) and which therefore is incapable of further reaction with oxygen, and (ii) the anionic component is similarly not capable of further reaction with oxygen. This substance can thus be designated as non-flammable. (Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, section R.7.1.10.3)
Pyrophoric properties
Testing for pyrophoric properties is not considered to be required, since strontium oxide is stable at ambient temperature. It does not contain any chemical groups that might lead to spontaneous ignition a short time after coming in contact with air at room temperature (ca. 20 °C) . Furthermore, long-term industrial experience in handling shows that strontium oxide does not ignite in contact with air (in accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1).
Flammability in contact with water
The study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture. Strontium oxide dissolves in water under formation of a stable hydroxide.
Justification for classification or non-classification
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.
