Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Terbium trinitrate did not melt over the temperature range tested (-68°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 endothermic peaks at 71.7 °C and 89.5 °C at 97.0 kPa. These endothermic events 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 terbium trinitrate in terbium oxynitrate.
