Die Substanzen zeichnen sich durch Blei- und Bariumfreiheit aus, einer hohen AnzĆ¼ndleistung, kurzen Reaktionszeiten und entsprechenden Empfindlichkeiten. Diese Eigenschaften ermƶglichen eine Reduzierung der zur sicheren AnzĆ¼ndung benƶtigten Masse an Explosivstoffen.The substances are characterized by lead and barium freedom, a high ignition power, short reaction times and corresponding sensitivities. These features enable a reduction in the mass of explosives needed for safe ignition.
In Tabelle 1 sind Zersetzungstemperaturen, Reib- und Schlagempfindlichkeiten ausgewƤhlter Beispiele dargestellt. Die Messung der Reib- und Schlagempfindlichkeiten erfolgte nach Methoden der Bundesanstalt fĆ¼r Materialforschung (BAM) angeben im BAM-Bericht 142 (1987), wƤhrend die Messung der Zersetzungstemperaturen mit der Dynamischen Differenzkalorimetrie (DSC) (Fa. Mettler) bei einer Aufheizrate von 10 K pro Minute erfolgte.Table 1 shows decomposition temperatures, friction and impact sensitivities of selected examples. The measurement of the friction and impact sensitivities was carried out according to methods of the Federal Institute for Materials Research (BAM) in the BAM Report 142 (1987), while the measurement of the decomposition temperatures by differential scanning calorimetry (DSC) (Mettler) at a heating rate of 10 K. per minute took place.
