By and large, a mixture of 1:1 by volume, given equal grain size, will give you adequate results, but 8:3 iron:aluminium by weight gives you the best bang for the buck.
Ive always found that 8 grams of iron oxide to 3 grams of aluminum is the best mixture for thermite, but then again I haven't experimented all that much.
@neocronick old comment but you're correct. 8:3, if thoroughly mixed, is the most efficient ratio. More Iron Oxide may compensate for larger powder size or incomplete mixing, but any less will leave you with unoxidized aluminum.
hahaha! im not an expert but, i have just completed a course on physical chemistry. yes, steam can be very dangerous but not an invisible cloud that would distroy your hand. just some lovely (and painful) burns. always use caution. if its red, its still hot. if it was red 2seconds ago, its still hot.
I'm pretty sure you don't know what you're talking about here.
It's nigh impossible to make superheated steam at ambient conditions. If it were a pressurized vessel in which it had a finite amount of water, yes it could make superheated steam. Otherwise it will just be a larger volume of your typical, run of the mill 212 degree steam.
Adding enough water should remove most of the heat and should be able to stop the reaction, especially due to the activation energy of the reaction.
If you'r thermite is of a decent quality/mixture ratio- it should get hot enough to split water molecules into hydrogen and oxygen, thus fueling the reaction.
dude don't put water and thermite together. the water turns into super heated steam and will literally burn your hand to crumbles. and it is invisible . and there is no point of being safe and putting the thermite out with water because it is impossible to put it out
I don't know what you're going on about. There is not any water in this video. Hot iron will not create super heated steam that is invisible. And it is possible to put thermite out and/or cool the iron down with.
I've used roughly a 3:1 ratio of iron oxide to aluminum and mine works quite well. So I'd say the 2nd is maybe the best. That ratio though is for Fe2O3 (red iron oxide or rust), if you use Fe3O4 (black iron oxide) the ratio is different.
yeah the second was most even burn, but the third got the hottest. as it actually broke the glass. so it really just depends on what you are looking to get out of the reaction

ok for those of you who want to make dont know chem IM me ill give you the perfect (i mean perfet to the 4th decimal) recipe
all i need is:
the about you want to make (ill tell you what you need to buy)
or
the amout of aluminum and Fe2O3 (rust) you have
i will give substitutes if you want such as (FeO4)

yeah there is water in the video it is right under the metal that you are holding the container up with, and you can hear it running
but any way yeah if you make thermte properly it and put water on it, it will make super heated steam,
i don't care if you don't know what you are doing

which is better fro thermite Fe3O4 or Fe2O3
johnnycyork 4 years ago
From what I understand, Fe3O4 will give a hotter reaction.

74.7% Fe2O3 + 25.3% Al or
76.3% Fe3O4 + 23.7% Al
both close enough to use 3:1 ratio
boneleg 4 years ago
2nd one definitely, most steady burn, but hwat were the ratios; and is that by wieght or volume?
Darcshadow5 4 years ago
First: 2+2/3:1 (2.67:1)
Second: 3:1
Third: 3+1/3:1 (3.33:1)
Ratios are by mass.

THe second looked hottest. I thought the correct ration was 2:1 iron oxide to aluminum?
Jangle2007 4 years ago
3:1 Iron Oxide to Aluminium respectively...

I'm guessing the last one had the right stoichiometric ratio of FeO2 to Al.
RichardC111165 4 years ago
Well, it's actually Fe_2O_3, I think the last one was 2 and 1/3:1 of iron oxide to aluminum.

It was a 3 1/3:1 ratio. Sorry.
