| Abstract: |
| Particle size, morphology, specific surface area and effective aluminum content of three kinds of aluminum powders were tested. The combustion improver of ferrocene, boron powder, ammonium perchlorate, fluororubber F246, Fe2O3, and perfluoro surfactant HX-12 were selected to investigate the combustion-supporting effect of combustion improver on aluminum powder at high temperature by DSC. The results show that boron powder has the best combustion-supporting effect. The addition of boron powder increases two exothermic peaks of aluminum powder. When the content of boron powder is 10%, the total heat release is more than 2 times than that of pure aluminum powder FLQT-4. |
