Effect of amine-modified boron nitride (BN) on ammonium perchlorate decomposition Academic Article uri icon


  • © 2016 The Royal Society of Chemistry. Solid propellant is an important material in space exploration. It is also used in the automobile and demolition industries as well as in ejection seats and airbags where precise control of burning rate is crucial. In the present work, a novel multiphase boron nitride (BN) material containing NH2was synthesized and found to have a large impact on energetic materials. The reaction of the BN material with solid oxidizer ammonium perchlorate (AP) was characterized using DSC/TGA, SEM, XPS, and a high-pressure propellant strand burner. Primary amine groups on the BN material participates in a chemical reaction with the AP crystals causing a dramatic weight loss during low-temperature decomposition which is important for high-precision applications. While the burning rates of propellants containing 0.5% of the micron- and nano-sized BN materials increased by about 30% over the baseline formulation with no BN, similar propellants containing the synthesized BN material decreased the burning rate by as much 25%.
