Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- > 400 °C
Any other information on results incl. tables
The absence of any significant thermal events and the unchanged physical state/appearance of the test material residue on completion of each determination confirmed that no phase transition occurred. Therefore the melting temperature of the test material was greater than 400°C, >673 K.
