Type of method:
thermal analysis
Remarks:
Differential Scanning Calorimetry
Melting / freezing pt.:
> 723 K
Remarks on result:
other: ± 0.5

The absence of any significant thermal event indicated that there were no changes in the physical state of the test material over the temperature range of 25 to 450 °C. The melting temperature of the test material has been determined to be > 723 ± 0.5 K.

Conclusions:
The melting temperature of manganese oxide has been determined to be > 723 ± 0.5 K.

Description of key information
