DIFFERENTIAL SCANNING CALORIMETRY METHODS IN THE DETERMINATION OF THERMAL PROPERTIES OF EXPLOSIVES

Abstract

Differential Scanning Calorimetry methods are applied in determining heat of fusion, purity, specific heat, and activation energy of decomposition for undiluted, unmixed samples of the high explosives TNR, TNT, tetryl, HMX, RDX, and PETN. Thermograms describing energy absorption or evolution from 300K to 600K are presented. Heat of fusion and purity results are consistent for explosives which melt at lower temperatures without vaporization, such as TNT and tetryl. Specific heat values in the 313K to 423K range all lie between 0.25 and 0.35 cal/gm K, monotonically increasing with temperature. Activation energies obtained are 20% to 50% higher than those reported from isothermal tests.
