Abstract

Solid oxidizer particles of ultrahigh surface area are produced by an etching process which includes employing selective extractants in a process which causes the formation of indentations and/or cavities on the surfaces of the oxidizer particles, and crevasses and tunnels in the oxidizer particles. The method is particularly attractive for manufacturing ultrahigh surface area ammonium perchlorate which has limited solubility in the extractants ethanol, butanol, or a mixture of these extractants.
