Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 23 May 2016 - 31 August 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Remarks on result:
- no self ignition observed under the test conditions
- Remarks:
- (up to 400°C)
- Conclusions:
- The self-ignition temperature of tris[oxalato(2-)]digadolinium 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.
Reference
At the start of the test, the test item was a white powder.
At the end of the test, the cube was half-full of yellow powder. This change may be due to the loss of hydration water from the test item and its decomposition which were observed around 100°C and 140°C and 275°C - 325°C respectively during the melting point study (study report No. 16-919080-001).
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.
Description of key information
In a GLP study performed according to the EU A.16 method (Klimisch 1, Demangel, 2016), 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.
This study was assigned as key study.
Key value for chemical safety assessment
Additional information
At the end of the test, the cube was half-full of yellow powder. This change may be due to the loss of hydration water from the test item and its decomposition which were observed around 100°C and 140°C and 275°C - 325°C respectively during the melting point (study report No. 16-919080-001).
