Principles of method if other than guideline:
Melting points were determined in an atmosphere of dry argon by the method of thermal arrests with the apparatus described by Bell and Masson, 1964.
Type of method:
thermal analysis
Melting / freezing pt.:
1 473 °C
Conclusions:
The melting point of strontium fluoride, determined using the method of thermal arrests as decribed by Bell and Masson (1964), was determined at 1473°C.

Description of key information

Melting points are reported in literature for the two main constiuents which make up >99% of the substance. The melting point of the substance is expected to lie inbetween the melting points of BaF2 (1290 -1355°C) and SrF2 (1473°C).

Key value for chemical safety assessment
