Self heating in consolidated A1/Cu/sub 2/O thermites

The ignition theory of Frank-Kamentskii, which follows from a solution of the steady-state heat flow equation for an isotropic chemical heat source, predicts that a measurable temperature difference will be established between the center and wall of a sample that is near its ignition point. This temperature difference was measured in a cylindrical Al/Cu/sub 2/O thermite part under conditions approximating a steady-state. The results of the measurements lead to a calculation of the activation energy and a pseudo-zero order preexponential factor for the thermite reaction rate constant.
