Results and discussion
Melting / freezing point
- Key result
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: No melting temperature was found between -120 °C and 40 °C
Any other information on results incl. tables
No melting temperature was found between -120 °C and 40 °C, even by addition of aluminum oxide powder as crystallization aid and annealing at -110 °C and -90 °C (determination Test 2).
Below -100 °C a glass transition was visible with an approximate value of -115 °C. Further analysis was not possible because the start of the glass transition lay outside of the instrument measuring range.
The estimated accuracy is ± 1 °C.
Applicant's summary and conclusion
- Conclusions:
- No melting temperature was found between -120 °C and 40 °C, even by addition of aluminum oxide powder as crystallization aid and annealing at -110 °C and -90 °C.
