Abstract

The thermal decomposition behavior of high explosive CL-20 was determined by microcalorimetry method, and the thermal decomposition behaviors of CL-20 with BTATz or BTATz and aluminum at different heating rates were studied at the same time. The kinetic and thermodynamic parameters were obtained from the analysis of the heat flow data. Critical temperature of thermal explosion (T b) and initial decomposition temperature (T p0) were calculated to show the effect of the aluminum on the whole system.
