Two DSC measurements were performed.
No endothermic event was detected in both measurements, except an unsteady baseline between 159.12 °C and 229.56 °C in the second measurement. The unsteady baseline could be a sign of splitting of a chemical compound.
Likewise, no signs of melting were seen when heated on magnesia groove.
Therefore, the melting point should be stated as >600 °C under these test circumstances.
Two DSC measurements were performed.
No endothermic event was detected in both measurements, except an unsteady baseline between 152.82 °C and 232.21 °C in the second measurement. The unsteady baseline could be a sign of splitting of a chemical compound.
Likewise, no signs of melting were seen when heated on magnesia groove.
Therefore, the melting point should be stated as >600 °C under these test circumstances.
Two DSC measurements were performed.
In both measurements no endothermic event was detected, except an unsteady baseline between 141.52 °C (lowest value) and 212.83 °C (highest value). The unsteady baseline could be a sign of splitting of a chemical compound.
Likewise, no signs of melting were seen when heated on magnesia groove.
Therefore, the melting point should be stated as >600 °C under these test circumstances.
