Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
The density of CaB6, calculated based on pycnometric analysis, is 2.33-2.43 g/cm3 and 2.43-2.52 g/cm3 based on x-ray data.
Executive summary:

The density of CaB6, calculated based on pycnometric analysis, is 2.33-2.43 g/cm3 and 2.43-2.52 g/cm3 based on x-ray data. Because this data is available in a handbook, it is considered reliable with restrictions.

Description of key information

The density of CaB6 is 2.33-2.43 g/cm3 (pycnometric analysis).

Key value for chemical safety assessment

Additional information

An additional density of 2.43-2.52 g/cm3 is available based on x-ray data. Because these data are available in a handbook, they are considered reliable with restrictions.
