Thermite - Wikipedia, the free encyclopedia
Sounds like fun stuff. Quite popular on a lot of science programmes.

The one i learnt years ago was something like Potassium permanganate + ammonium nitrate + brake fluid + wrap in a tin foil ball = v hot reaction with a delayed ignition.Originally posted by TimberWolf View Post

I didn't say it was your ******* fault, I said I was blaming you! -
One of the more fun chemistry demos we had at school - not sure if they still allow it. We all trekked out to the sports field for the teacher to light a proper cup-full of the stuff in a very heavy duty iron cup/flask in the long-jump pit (jeez this sounds like a GricerBoy thread). The container was melted clean through

Aluminium and iron oxide (rust) is the commonest and preferred mixture I gather, and the ones they use on TV. Might be handy stuff to have around for a bit of spot welding.Originally posted by d000hg View PostOne of the more fun chemistry demos we had at school - not sure if they still allow it.

Seems to me that aluminium oxides to aluminium oxide (alumina) the instant you would make a powder out of it. Do you know whether aluminium is prevented from oxidising somehow in thermite mixes, or whether alumina works?Comment

I vaguely recall it has to be unoxidised but I'm not sure - I can't remember if I'm confusing it with how potassium was kept in oil. Maybe you just need a bit of it unoxidised to start it going.Originally posted by MaryPoppinsOriginally posted by vetranComment

LOL, was just looking up home made examples and happened to see how easy it is to make other really dangerous stuff such as chlorine gas, mustard gas, chloroform... Bleach seems to crop up a lot. Don't try this at home kids.Comment
