With the substance

1. as delivered, a self-heating was not detected until 420°C. Above the melting point the test item melted and flew out of the wire basket without showing an oxidising reaction.

2. in mixture with kieselguhr (1:1) a first reaction was detected at 270°C which was intensified from 300°C to a maximum temperature of 600°C. The beginning of the reaction at 270°C corresponds to the exothermal reaction in the thermal stability test (closed glass crucibles).
