Ignition of boron-containing high-energy materials based on an oxidizer and polymer binder
The use of aluminum borides is a promising direction in the development of modern propellant compositions and aerial vehicles. We present experimental data on the kinetics of oxidation of microscale powders of aluminum, amorphous boron, and the aluminum borides AlB2 and AlB12 in air upon heating at...

| 520 | 3 | |a The use of aluminum borides is a promising direction in the development of modern propellant compositions and aerial vehicles. We present experimental data on the kinetics of oxidation of microscale powders of aluminum, amorphous boron, and the aluminum borides AlB2 and AlB12 in air upon heating at a constant rate of 10°C/min and the results of laser-assisted ignition of high-energy materials that contain these metal powders and are based on ammonium perchlorate, ammonium nitrate, and an inert binder or an energetic combustible binder. We show that the use of the boron-containing powders enables us to lower the onset temperature of oxidation and the temperature of intense oxidation, while increasing their oxidation effectiveness, compared to pure aluminum. The dependences of ignition delay time on the heat flux show that the AlB2 and AlB12 powders are the most effective metal fuel components for solid propellants based on ammonium perchlorate, ammonium nitrate, and an energetic binder: they display the shortest ignition delay time and require the lowest heat input for ignition. | |
