- Remarks on result:
- other: The test material did not melt at temperatures up to 723 K
- Conclusions:
- The melting temperature of MnO2 has been determined to be > 723 ± 0.5 K (> 450°C).
- Executive summary:
The melting point of the test material was investigated in a study which was conducted in accordance with the standardised guideline EU Method A.1.
Under the conditions of the study the melting temperature of the test material was determined to be in excess of 723 K.
Reference
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.
