Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Executive summary:

The relative density of aluminium oxide is 3.5 -4.0

Description of key information

A weight-of-evidence approach was used to address this endpoint. Values obtained from 8 separate sources varied from 3.2 - 4 gm/cm³.

Key value for chemical safety assessment

Relative density at 20C:
4

Additional information

All available data sources agree that the density of aluminum oxide is on average approx. 4 gm/cm³.
