ABSTRACT:
A method for improving the combustion efficiency, i.e. increasing the burning rate, of propellant, flare, and other pyrotechnic compositions is disclosed which comprises using at least some ammonium perchlorate oxidizer coated with aluminum metal in place of a mere mixture of aluminum and ammonium perchlorate. The resultant compositions have increased burning rate in comparison to mere mixtures of ammonium perchlorate and aluminum.
