Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key result
Remarks on result:
no self ignition observed under the test conditions
Remarks:
up to 400 °C

At the start of the test, the test item was a white powder. At the end of the test, the powder remained white.  

The temperature of the test item sample followed the temperature of the oven up to the highest oven temperature reached (400°C).

Similar observations were made in the two assays.

Conclusions:
The self-ignition temperature of lutetium oxide was investigated according to the EU A.16 method in compliance with GLP. No self-ignition temperature was observed up to 400°C (corrected value). The temperature of the test item sample followed the temperature of the oven.

Description of key information

Based on a GLP study (K1, Demangel, 2017) using the EC A.16 method, no relative self-ignition temperature of the test item was observed up to 400 °C (corrected value).

Key value for chemical safety assessment

Additional information

No relative self-ignition temperature was observed up to 400°C
