Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Type of information:
other: Secondary literature
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Secondary literature, handbook with reliable values.

Density:
5.45 g/cm³
Temp.:
20 °C
Type:
relative density
Density:
5.45
Temp.:
20 °C

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 sulphide has a relative density of 5.45.

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 sulphide has a relative density of 5.45.
