Description of key information

A weight-of-evidence approach was used to address this endpoint.  The values from the 4 sources were consistent.

Key value for chemical safety assessment

Vapour pressure:
1 hPa
at the temperature of:
2 158 °C

Additional information

This assessment relates to the main component, aluminium oxide, and the assessment of the reaction mass based upon its main component can be considered as a worst case approach. Generic issues relating to inorganic substances can be considered as appropriate for all other components within the reaction mass.

All available data sources agree that the vapour pressure of aluminum oxide is 1 hPa at 2158 °C.
