Description of key information
All experimental and literature data indicate no oxidizing properties.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
- Aluminum Oxide which is the main constituent of Al dross, is among the most stable oxides as shown in Ellingham diagram.
- It should be noted that no self-ignition temperature was observed up to the maximum test temperature of 405 °C, according to the testing guideline for auto-flammability (solids - determination of relative self-ignition temperature) (endpoint 4.12).
- Substance remained unchanged after contact with flame.(endpoint 4.13)
-
The
DSC-measurement in a closed glass crucible with the test item showed
no exothermal effects in the temperature range 25 – 500 °C.(endpoint
4.14)
All experimental and literature data indicate no oxidizing properties.The substance has no auto-flammability, flammality nor explossive properties.
Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
