Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The atmospheric pressure during measurement is not reported. It is assumed that the melting point was determined at an atmospheric pressure of 101.325 kPa.

Conclusions:
According to the reference, cobalt sulphate has a melting point of >700 °C.

Description of key information

Melting point of cobalt sulfate (handbook data): > 700 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
700 °C

Additional information

For the evaluation of this endpoint data from one handbook were used. According to the REACH regulation (“ECHA, guidance on information requirements and chemical safety assessment – chapter R.7a”), it is allowed to use specific handbook data as a reliable data source. Useful reference books and data compilations containing peer reviewed physico-chemical data include the Merck Index.
