Thermite

[boris_73]

are dragon egg's made from minimum red lead and aluminium or PbO and aluminium because i was thinking of making them next

DON`T!, it`s a grade A way to win a Darwin award! (

 

here`s a question for you all, how come I was trained spelling it as "Thermit" and you lot spell it as "thermitE" with an E at the end?

 

what`s the diff (other than the obvious) and Why?

[jdurg]

'Thermit' is, I believe, a trademarked name for a product which produces a thermite reaction. 'Thermite' is the scientific name for it. I just read about this last night. When I get home from work I'll try and find that link again.

 

EDIT: Here we go. Thermit is a trademarked name, while Thermite is the name of the reaction.

i know the lead oxide thermites are dangerous but i was thinking only a few grams eg 3-5g and a full sparkler which would give me about 1 minute to get away i just want to do it for the experience in all the different thermites i have already tried the copper oxide and iron oxide one thats why i wanted to try the lead oxide one

[YT2095]

3 to 5 grams of the correct mix, you`de need a good distance!

it`s powerfull, but also more importantly LOUD!

 

one could easily think it actualy Detonates, it doesn`t, but it`s about as powerfull as it gets for a redox reaction in solid form

 

 

(and no before anyone jumps on the badwaggon to try correct me, there IS more powerfull redox in solids, but it`s a Thermit discussion!)

1. how loud is loud eg flash powder in a cardboard tube loud or louder

2. is there another name for it because i carnt find anything on google

[YT2095]

it`s more brissant than Flash powder (the 70/30 alu chlorate type).

it`s higher pitched, like a *CRACK* but don`t let that fool you!, it`s still Loud!

[Gilded]

I thought they use a more stable and safe mix these days than the red lead - alu composition in dragon eggs?

[boris_73]

wow so its better then flash powder, i never knew that, that is why i think i will only make a very small sample if i were going to make it

[boris_73]

I thought they use a more stable and safe mix these days than the red lead - alu composition in dragon eggs?

they use a less toxic chemical if thats what you mean by safe mix

[YT2095]

they do, and I`ve pointed this out before AND stated what is used instead, but no one seems to want to listen! (

[boris_73]

the chemicals which they do use in the safer mix are also a little harder to get hold off and more expensive then the red lead and aluminium, other wise if i knew where to get them they would be the chemicals which i would use for the dragon eggs

[YT2095]

I`de reccomend NOT making it until you can obtain the correct chems, but that`s going to fall on deaf ears too! (

[boris_73]

hold on i have just had a look and what i thought were the new safer chemicals were in fact not them anyway i can get hold of red lead aluminium ect now i just need to find what the new safer ones are where did you post saying what the chemicals were YT

[YT2095]

fair enough try this post I made not so long back:

 

I don`t recommend using red lead as it`s impact sensitive' date=' the beta-modification will make a reasonable thermite though, red lead Dragon eggs aren`t used anymore nowdays in Pyro, it`s been replaced by Bismuth Trioxide instead.

 

 

 

dissolve your lead in nitric acid making lead nitrate, then add sodium hydroxide, to make lead hydroxide and sodium nitrate, filter out the lead hydroxide and dry it, with heating the hydroxide will turn into Yellow lead

 

 

 

Lead Compounds are Toxic!!!!![/quote']

[boris_73]

does bismuth trioxide give the same effects ect

[jdurg]

Quite literally too!

[YT2095]

does bismuth trioxide give the same effects ect

of course! )

 

and LOL @ jdurg, I never realised when I posted that, well spotted )

[boris_73]

where can you buy bismuth trioxide because i can not get that, or what is it used in eg if used in pottery i would be able to get it from a pottery supplie shop

[Gilded]

Hmmh... I wonder if just burning bismuth in a pure oxygen atmosphere would yield bismuth trioxide.

 

Or then no, since it seems quite complex (Bi4O6). Looks kinda like hexamine.

[Lance]

Bismuth trioxide (Bi2O3) is that stuff that’s floats to the top and wont melt whenever you melt bismuth.

 

Look at my AIM screen name.

[Gilded]

"Bismuth trioxide (Bi2O3) is that stuff that’s floats to the top and wont melt whenever you melt bismuth."

 

I thought that it's Bi2O3, but ChemFinder told me that it's Bi4O6. Ahh well...

[folder]

Same empirical formula, so it shouldn't matter too much.

[budullewraagh]

well.....i wouldn't say that...formaldehyde and glucose have the same empirical formula but theyre totally different

[Gilded]

Yeah, it's quite important to have the right structure too when discussing individual molecules.
