ABSTRACT:
A wet mixture of a metal azide having a predetermined average particle size and a metal oxide is prepared. The wet mixture is ground to reduce at least the average particle size of the metal azide. Thereafter, the wet mixture is directed through a chamber containing grinding media. The grinding media is agitated as the mixture flows through the chamber to further reduce the average particle size of the metal azide to a desired particle size.
