  • Carbon treatment of reclaimed ammonium perchlorate
    Patent number: 5346512
    Abstract: A process for treating reclaimed ammonium perchlorate with carbon to produce rounded particles upon recrystallization is disclosed. In the process, a recovered ammonium perchlorate solution is contacted with activated carbon, preferably by passage through a packed column. Contamination that modifies the ammonium perchlorate crystal habit and causes rhombic-shaped ammonium perchlorate particles is removed by activated carbon. The carbon-treated ammonium perchlorate solution produces rounded AP particles upon recrystallization with mechanical agitation.
