Solid Energetic Material Based on Aluminum Micropowder Modified by Microwave Radiation

The paper discusses the application of pulsed microwave radiation for modification crystalline components a high-energy material (HEsM). model aluminized mixture with increased heat combustion was studied. contained 15 wt.% aluminum micron powder, which modified by irradiation. It found that HEM thermogram has an exo-effect maximum at 364.3 °C. use powder in composition energy release during 11% from 5.6 kJ/g to 6.2 kJ/g. reason this effect is increase reactivity after In research, we confirmed powders do not lose stored energy, even as part produced on their basis. A laser projection imaging system brightness amplification used estimate speed front propagation over surface. Measurement burning rate revealed slight difference rates HEMs based irradiated and non-irradiated micropowders. This property can be demanded practice, allowing greater while maintaining volume energetic material.
