Description of key information

Samarium trinitrate did not melt over the temperature range tested (-60°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 76.5 ± 0.2°C. 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.
