The work presented is an initial step in the attempt to obtain higher burning rates with nitramine‐based propellants. We have studied the influence of some boron and sodium compounds on the decomposition mechanism and on the burning rate of HMX. Results indicate that additives such as hydrazine monoborane, sodium boron hydride and methylamine monoborane lead to a significant increase of the decomposition heat of HMX and reduce as well as the activation energy and the temperature of maximum decomposition rate. Experimental results about r b (p) and r b (T o ) laws of HMX and HMX/additive mixtures are presented. Quantitative investigations show that the burning rate of HMX can be increased by approximately a factor of 3 by addition of 10% boron compounds. Moreover, the pressure exponent is reduced from 0.9 to 0.6.
