Abstract

By means of TG, DTG, and DTA, it was shown that the source of carbon can affect the decomposition and reaction characteristics of black powder compositions. Carbons with high volatile content lower the activation energy and reduce the ignition temperature of black powder. The removal of these volatiles causes an increase in ignition temperature and activation energy. It also showed that although sulfur has no effect on the ignition temperature, it does affect the preignition reaction. Sulfurless black powder also has larger activation energies than regular black powder. Compositions of black powder containing channel black have lower activation energies than those with charcoal.

    The dependence of the oxidation pathway on the temperature shows the complexity of the phenomenon and the necessity of considering other parameters as contributing factors. The active surface area of the carbon particles has been considered an effective parameter on the oxidation mechanism [16–20]. It is shown that edge sites and defects on the CB surface, i.e., active sites, depend upon the size of the particles, i.e., surface area.

    The presence of two DTA peaks (maxima at 641 °C and 784 °C) suggest that the oxidation proceeds in two steps. It is known that the oxidation rate of carbonaceous materials in air is strongly dependent on parameters such as surface area and crystallographic structure [19,20]. Defect sites in graphite contribute to a decrease in the oxidative stability of this material.
