Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- > 500 °C
- Decomposition:
- yes

Any other information on results incl. tables
In the TG/DSC curve of the melting test endothermic peaks are observed at the temperature ranges 253 – 287 °C, 290 – 314 °C and 879 – 923 °C. The mass of the sample decreases, when the sample is heated from ~250 °C up to ~450 °C and again when the temperature is more than ~870 °C. These peaks indicate decomposition step by step and melting, too.
Applicant's summary and conclusion
- Conclusions:
- There is no evidence of melting of the substance below at least 500°C.
