H3 is probably the least sensitive chlorate composition, sensitive to friction and shock that is (I have tried hitting small samples very hard with a mallet hammer with no ignition, deflagration or explosion. I have also tried igniting it via friction and failed). My personal tests do not mean you should trust the information i have given - be careful.

It is however very sensitive to heat, flame, and sparks. I have never tested it with respect to static electricity, you should consider that it would be enough to ignite H3. I agree with Anders about H3' uses, and i know from personal experience that it does make good fuse. However, if you do make fuse with H3 you need to be cautious about the compositions/chemicals that it comes into contact with. If your not sure then look on the forum and elsewhere regarding chlorates.

Mixing of H3 is safer than other chlorate compositions, but you should never grind or mill it, i mix it by shaking it in a plastic pot with a snap on lid. Shaking is done gently and the pot is allowed to rest a few minutes before opening otherwise you get a cloud of dust which is very undesirable.

For my pvc rockets i use quick set cement(sets in 10mins), i have heard of similar products like pourstone. It comes as a powder that you mix with water to a paste or slurry consistency and sets rock hard. Erosion is minimal if any, with a KNO3/Sucrose propellant anyway. You should visit the Inverse Engineering website for more info on simple efficiant nozzles.

Thanks for the info guys.

Where did you you find out about Red P forming White P, that is something i have not heard of before and i would like to research it for myself, of course i'll search for information on my own but a particular source of information is always handy.

I currently keep it with a few other chemicals but not amongst any oxidisers.

You say that you would like to be a million miles away from red phosphorus, it sounds like you have had some personal experience with the stuff? Or is it just the dangers that you have read about that are stated in texts about Red P?

Are there any chemicals in particular that it should not come into contact with?

I have read quite a lot of pyrotechnic and chemical texts and phosphorus often has a special mention but any knowledge you can share even if it is obvious or you think i might already know it is welcome.

Hey guys,
Just wondering - are there any pyrotechnic uses for Phosphorous? What are its properties/dangers etc ? Just curious that's all!
Thanks

I have some phosphorus of the red variety. Mine is more of a claret colour than actual red. I havn't done many tests with it, but the powder on its own is quite flammable. I'll experiment with it some more one day. As for uses (that i havn't seen mentioned already): The striking surface of some match boxes has red phoshorus in it, and it is present in paper caps.
