The first DSC measurement in an aluminium crucible with a hole showed an endothermal effect in the temperature range of 70 – 160 °C. A 2nd measurement was conducted being stopped at 180 °C. It showed an endothermal effect within the temperature range 90 – 140 °C. After both measurements visual inspection showed that the test item was unchanged. The results of the DSC measurement are summarized in Table1.

Under consideration of the result from the DSC measurement it was concluded that the test item had no melting point and no boiling point at atmospheric conditions.

Executive summary:

The test item had no melting point and no boiling point at atmospheric conditions.
