Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Ytterbium trinitrate did not melt over the temperature range tested (-80°C to 600°C).
Key value for chemical safety assessment
Additional information
An experimental study of reliability 1 according to Klimisch, performed in compliance with GLP and according to EU method A.1 and OECD Guideline 102 by Differential Scanning Calorimetry, was selected as a key study.
The DSC curve revealed an endothermic peak at 55.7 °C at 97.0 kPa. This endothermic event reflected the fact that the rare earth salt solubilized in its hydration water. No melting behavior was recorded up to 600°C. The endothermic peaks observed from about 320 °C to 500 °C at 97.0 kPa correspond to the decomposition of ytterbium trinitrate in ytterbium oxynitrate.
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.
