1. More energetic
2. A better oxygen donor
But due to another fact, namely that the chlorine atom in the perchlorate is a "closed shell" atom, it is more stable and thus less inclined to give off its oxygen, at least as long as we are talking about LE, i.e. our kind of pyrotechnics.
So, what to do about it? Can one compensate for this outside the laboratory? There are potassium dichromate, manganese dioxide and zirkonium. The first two are catalysts and the third accelerates reactions by giving off tremendous amounts of heat when mixed with a composition and ignited together with it.
Suggestions?
