Reference
Two DSC measurements in aluminium crucibles with a hole showed an endothermal effect in the temperature range of 420 – 490 °C. After the measurements the test item was a black residue. The mass loss after the DSC measurements amounted to 22 % and to 30 %, respectively.
The results of the DSC measurements are summarized in Table1.
