- Conclusions:
- The melting behaviour of lutetium oxide silicate was assessed according to the EU A.1 method and OECD test guideline 102 in compliance with GLP using Differential Scanning Calorimetry (DSC). No melting point of the test item was recorded up to 600°C during the experiment.
Reference
Assay No. 1 (isotherm at 25°C for 5 min, heating ramp: 25°C to 600°C at 10°C/min):
The test item appearance remained stable, since a grey powder was observed after the experiment. No melting point of the test item was recorded.
Assay No. 2 (isotherm at 25°C for 5 min, heating ramp: 25°C to 600°C at 10°C/min):
The test item appearance remained stable, since a grey powder was observed after the experiment. No melting point of the test item was recorded.
Description of key information
In a GLP experiment assigned as key study (Klimisch 1, Demangel, 2017c) and performed according to the EU A.1 method and OECD test guideline 102, no melting point of the test item was recorded up to 600°C, using Differential Scanning Calorimetry. No decomposition was observed either. The melting point is considered to be > 600°C.
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
