Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Vapour pressure
Administrative data
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: The CRC Handbook of Chemistry and Physics contains information from authentic and highly regarded sources. Its many contributors come from throughout the world. The Handbook has been peer-reviewed by a sounded Editorial Advisory Board.
Data source
Reference
- Reference Type:
- review article or handbook
- Title:
- CRC Handbook of Chemistry and Physics, 78th Edition
- Author:
- David R. Lide, ed.
- Year:
- 1 997

Materials and methods
Test guideline
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- The method used for the determination of the vapour pressure refers to the publication C.B. Alcock, V.P. Itkin and M.K. Horrigan "Canadian Metallurgical Quarterly" 23, 309, 1984. We are confident that the source has been checked for reliability. The vapour pressure value described here correlates to our experience.

Results and discussion
Vapour pressure
- Temp.:
- ca. 970 K
- Vapour pressure:
- < 0 Pa
Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of cerium metal was determined to be 0,1 * 10-7 Pa at 970 K
- Executive summary:
We confirmed the melting point of cerium metal by comparing our experimental values with the values published in the CRC Handbook of chemistry and physics.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
