Results and discussion

Melting / freezing point
Key result
Melting / freezing pt.:
> 500 °C
Remarks on result:
other: No melting point could be determined via DSC (differential scanning calorimetry) up to a temperature of 520°C.
Remarks:
The test item changed the colour from white to grey in the pre-test.

Applicant's summary and conclusion

Conclusions:
No melting point could be determined via DSC (differential scanning calorimetry) up to a temperature of 520°C.
Therefore the melting point should be stated as > 500°C.
