Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Remarks on result:
other: relative density: 4.2

According to the reference, the density values can be assumed to refer to temperatures near room temperature. For this reason 20 °C was filled in as temperature.

The relative density was calculated from the value of the handbook. The value was divided by the relative density of water (1.000).

Conclusions:
According to the reference, cobalt carbonate has a relative density of 4.2.

Remarks on result:
other: relative density: 4.13

In the reference no temperature at which the density was measured was stated. It was assumed that the relative density was measured at 20 °C.

Conclusions:
According to the reference, cobalt carbonate has a relative density of 4.13.

Description of key information

The relative density of cobalt carbonate is given as 4.13 and 4.2. The mean value of 4.17 will be used for CSA.

Key value for chemical safety assessment

Relative density at 20C:
4.17
