Ignition and Combustion Performance of B@HMX Composite Microunit Prepared by Recrystallization of Solvent Evaporation.

ABSTRACT: Fuel boron (B) has the advantage of a high calorific value. However, a coating of boron oxide (B₂O₃) is present on the outermost layer of the B particles, which will greatly hinder the oxidation of B. In this study, the high-energy 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane (HMX) is used to increase the activity of B powder, so as to enhance the ignition and combustion performance of B. Samples with various HMX contents are successfully prepared by recrystallization of the solvent evaporation method. The study of morphology and composition reveals that HMX is coated on the surface of B particles to form composite microunits. Interestingly, the heat and gas released during the decomposition of HMX facilitated the evaporation and destruction of the oxide film. Conse
