Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Melting point: > 450 °C (EU Method A.1, OECD 102, GLP)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 450 °C
Additional information
The test material was determined to have a melting temperature greater than 723 K. The test material was identified as undergoing loss of volatiles, most likely water, due to dehydration of the test material, at approximately 389 K and 518 K. However, these thermal events were not associated with a phase transition (i.e. melting) of the test material.
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.
