Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Bismuth metal has a boiling point of >1560°C (handbook data).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 1 560 °C
Additional information
For the evaluation of this endpoint data from two handbooks (CRC handbook and Merck Index), one data base (Gestis database) and one material safety data sheet were used as a weight of evidence.
According to ECHA, guidance on information requirements and chemical safety assessment – chapter R.7a, specific handbook data for physic-chemical properties are considered to be a reliable data source. Useful reference books and data compilations containing peer reviewed physico-chemical data include the Merck Index and the CRC Handbook of Chemistry and Physics.
Data available from these handbooks describe a boiling point of 1420°C to 1564°C for Bismuth metal.
Concerning the available MSDS: According to the European Chemicals Agency, 2010 (Practical guide 2: How to report weight of evidence),values for physico-chemical properties taken from material safety data sheets (MSDSs) can only be assigned a reliability rating of (4), not assignable, unless detailed information such as the experimental methodology are provided to enable the preparation of a (robust) study summary. However, the value for the boiling point is in accordance with the information obtained from the CRC handbook.
Since all except one information source (Merck index: boiling point of 1420°C) describe a boiling point equal to 1560°C, this temperature is set as the key value for the chemical safety assessment.
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.
