Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Endpoint:
- melting point/freezing point
- Type of information:
- other: handbook
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Justification for type of information:
- Handbook data are considered from a trusted source. Data have been taken from many sources, including both compilations and the primary literature - where conflicts were found, the value deemed most reliable was chosen. The reference was peer-reviewed. In addition, the reference sources are indicated although not leading to sufficient information on the material & method used.

- Conclusions:
- The CRC Handbook of Chemistry and Physics (80th ed.) mentions a melting temperature of 561°C for calcium nitrate (anhydrous).
