Applicant's summary and conclusion
- Conclusions:
- In this handbook, a melting point of 996 °C is reported for sodium fluoride. This value is considered valid for an atmospheric pressure.
- Executive summary:
In this handbook, a melting point of 996 °C is reported for sodium fluoride. This value is considered valid for an atmospheric pressure.
According to the ECHA Guidance on information requirements and chemical safety assessment, Chapter R.7a: Endpoint specific guidance, the Sax's Handbook should be considered as a peer-reviewed handbook. Hence, these parameters are considered as reliable with restrictions.
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.
