Description of key information

The melting point is in the range of 840 and 845 °C at normal atmospheric pressure.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
845 °C

Additional information

A literature search was conducted and the available published data reviewed. In a weight of evidence approach the literature values were evaluated.

The literature search resulted in three independent values. The melting point was determined to be 845 °C (Hommel Handbook, query date 19 April 2016; Sax Handbook, 1992) and between 840 and 845 °C at normal atmospheric pressure (Gmelin handbook, 1960). All 3 independent values are in the same range and therefore regarded as reliable. A melting point of 845 °C was chosen as key value.
