Abstract
The possibility of burning of a mixture of chromium peroxide with aluminum nitride is shown experimentally. The effect of initial pressure of nitrogen and ratio of reagents on an average linear burning rate, as well as for the relative mass loss in the burning of a CrO3/AlN mixture. The concentration limits of the burning rate of the test mixture are determined. The microstructure and phase and chemical compositions of the combustion products of the chromium- and nitride-aluminum mixture are studied.
