Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 melting point of cesium chloride was determined to be 642 °C at 1013.25 hPa.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 642 °C
Additional information
The determination of the melting point was performed according to EU test method A.1 and OECD Guideline 102 by applying the differential scanning calorimetry (DSC). The heat flow curves of two measurements show a small endothermic phase change between 471 and 474 °C, and upon further heating, a sharp endothermic peak with a peak maximum temperature at 646 °C and an extrapolated onset temperature of 642 °C indicating the melting temperature at ambient pressure. Therefore, the melting point of cesium chloride was determined to be 642 °C at 1013.25 hPA.
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.
