Experience from manufacture and use suggest that there is no specific melting point and instead the substance will oxidise at high temperatures.

Conclusions:
Experience from manufacture and use suggest that there is no specific melting point and instead the substance will oxidise at high temperatures.
Executive summary:

Experience from manufacture and use suggest that there is no specific melting point and instead the substance will oxidise at high temperatures.

Description of key information

Above 300oC. Experience from manufacture and use suggest that there is no specific melting point and instead the substance may oxidise at high temperatures. The sample was heated to 400oC and no melting was observed.

 

During normal use and handling, and certainly under biological and environmental conditions, the substance will remain solid.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
400 °C
