Ah alas.It is completely unsuitible as an oxidiser in pyrotechnics. Some morons may come by and say they use it in flash and it works great, but alas, they are morons.
I used it once upon a time. When i didn't have access to KCl04 or Kno3.
No it won't ignite with water when in contact with S8, well not in my experience. I used it as a payload for my rockets. I dislike the stuff, and the "flash" can't really be called flash because it is incredibly slow for any kind of flash. My BP is faster now.
Yeah, don't use it. I've heard it can spontaneously ignite with S8, although it hasn't happened to me. It also stains like no tomorrow.

If at first you don't succeed, skydiving is not for you.

I find that it has a pretty good use: Making Iodine cristals with KI.

Just to point out a previous comment...KMnO4 can make some scary flash that is getting damn close to HE

I'm a firestarter, twisted firestarter... you're the firestarter, twisted firestarter.

Nah, i prefer my MgAl/KCl04 + 5% Ti Flash...KMnO4 can make some scary flash that is getting damn close to HE
Its so scary i hardly use it anymore.
Makes great salute payloads for rockets though, sounds like the sky is splitting in half.

I know that much higher purity H2O2(70%+) has been used as a mono-propellant in rockets and is what rocket belts use for fuel as it decomposes on silver mesh/screens. KMnO4 and 70%+ H2O2 is pretty much a detonation so it isn't used, I believe they call it explosive decomposition. 35% H2O2 and silver has very little reaction so it also has no use. What I hope to do is use 35% H2O2(because anything above that is hard to find) and KMnO4 as fuels because they are reactive enough to create thrust and are relatively easy to get. When I design hybrid or liquid rocket engines I try to make the components easy enough to get that the the engine could easily be built anyone who has the tools to do it(usually a lathe is needed). And yes, I have designed and built a hybrid engine before.Oriansbelt; I dunno about the rocket, you would need a lot of KMnO4 and H2O2, and I dont think it would produce enough pressiure to make the thing take off with the payload that's flerf (KMnO4 and H2O2 that hasent been consumed)
So to repeat my question, how/where did u find that KMnO4? I still won't be able to do enough tests to prove my concept of the engine till I get an easy source of KMnO4.

Concentrated peroxide/permanganate fuels are FAR above my pay grade, but it sounds pretty dodgy to me. Good luck, and stay safe.

I think so.http://www.trickz.co.uk/flash-demo.wmv
That scary?
Now its all gone, i love using them in Cup Set salutes...

Just out of curiousity. What kind of flash is that? It scared me while I was in the safety of my own home and watching it on the computer.http://www.trickz.co.uk/flash-demo.wmv
