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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Justification for type of information:
- Assessment made by manufacturer and corresponds to handbook date.
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Principles of method if other than guideline:
- Maplelab Scientific Melting Point Device MPD02
- GLP compliance:
- no
- Type of method:
- capillary method
- Specific details on test material used for the study:
- Batch number of test material : Z-09-2715
- Key result
- Melting / freezing pt.:
- > 500 °C
- Decomposition:
- yes
- Remarks:
- To chromium oxide
- Decomp. temp.:
- > 300 °C
- Conclusions:
- Above 300 oC. Experience from manufacture and use suggest that there is no specific melting point and instead the substance will oxidise at high temperatures. This was confirmed by heating to 500 oC with the formation of chromium oxide
- Executive summary:
Above 300oC. Experience from manufacture and use suggest that there is no specific melting point and instead the substance will oxidise at high temperatures. This was confirmed by heating to 500oC with the formation of chromium oxide.
During normal use and handling, and certainly under biological and environmental conditions, the substance will remain solid.

Additional information
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.
