Abstract
Boron (B) powder has been considered a promising high-energy material due to its high calorific value. Nevertheless, the low combustion efficiency and the difficulty in ignition restrict its application. To solve the problems, in this study, an energetic metal-organic framework (EMOF) was used as a modifier for the nano-sized B powder, and its effect on the ignition and burning performance of B powder was examined. EMOF can significantly increase the heat release of B powder and lower its initial oxidation temperature. The best improvement is achieved with 10% EMOF contents in air, while the highest heat release is obtained with 25% EMOF contents in pure oxygen. Furthermore, EMOF can also reduce the ignition delay of B powder, enhance the flame intensity, and increase the flame propagation rate. This study offers new perspectives on modifying B powder with incorporating EMOF to develop multifunctional energetic particles with improved ignition and combustion characteristics.
