no

Type of method:

capillary method

Key result

Melting / freezing pt.:

> 400 °C

Decomposition:

ambiguous

Remarks:

To chromium oxide

Decomp. temp.:

> 400 °C

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 300^oC. 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 400^oC 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
