Abstract
The specifics of the combustion of micron-sized flaky aluminum powder in mixtures with crystal-line hydrates over a wide pressure range at various mass ratios between aluminum and crystalline hydrate are studied. Limiting conditions of combustion of mixtures regarding the composition and pressure are determined. With use of a stoichiometric mixture of aluminum with sodium sulfate crystalline hydrate, the coupled combustion composite samples with additional oxidants, ammonium nitrate and potassium nitrate, and samples with spread oxidant is examined. It is established that the velocity of coupled combustion can significantly exceed the velocity of combustion of the base mixture. Limiting conditions for combustion of mixtures are determined.
