Posted 12 April 2024 - 04:54 AM. Ammonium perchlorate forms a more shock sensitive coordination compound with copper metal, just like ammonium nitrate does, and its thermal decomposition is also catalyzed by zinc dust and probably by some other metals. So it's best to make sure that the balls and the inner surface of the mill are not …

Potassium Perchlorate can be set off on it's own, much like potassium chlorate. However, this results in partial detonation, and the force required is orders of magnitude higher than what it would have experienced in that particular ball mill. The answer to all of these inquiries is of course to ball mill remotely.
