In order to achieve predictions with a high degree of confidence concerning the thermal behaviour of high-energy materials, the heat-generating process in the inhomogenous thermal conduction equation is described by a one- to four-step reaction process. Deconvolution and kinetic analysis, using multivariate non-linear regression of DSC measurements together provide the basis for relevant kinetic parameters to describe the thermal behaviour of Zoalen above the melting temperature. It is shown that only when one has a combination of DSC measurements and measurements with highly-sensitive micro calorimeters, can predictions with a high degree of confidence be achieved over the entire temperature range.
