Thermite

[boris_73]

the ferric thermite, is one that burns about 2000-2500c slowly and leaves molten iron behind, its also used in welding the lead oxide thermite burns very fast leaving very little residue behind a much better reaction to see, it is also ment to explode so if i were to do this reaction i think ill run as soon as a magnesium ribbon is lit, it is also much more easer to ignite then the ferric thermite, is i think it can be ignited from flame

which would work better as a thermite reaction, faster reaction

lead(II)oxide+magnesium

lead(II)oxide+aluminium

lead dioxide+magnesium

lead dioxide+aluminium

i would say that lead dioxide and aluminum would but i cannot be sure. the way you powder/mix your reactants also has a great effect

I made plaster thermite today and I must say it’s pretty entertaining. It’s easier to light because you can shape it unlike ferric thermite.

would lead oxide (litharge) be ok to use in the lead oxide thermite because litharge is used in making rubber ect but it still has about 98% purity maybe more, if so i can get 500g for about £5.00, also lance did the Plaster thermite explode like it says it would

It didnt really explode because my thermite was crap. I was surprised that it reacted as well as it did. I added too much water and spilled most of it all over the place and it seperated. I just bought decent aluminum powder also so Ill see how that works out.

do you have the instructions to make plaster thermite because if lead oxide thermite can explode unconfined i would love to see it when it is confined

Nope, not really. I had just heard it was possible and I mixed it in a random ratio that looked good then mixed it together with a bit of water (which turned out to be too much).

 

Even if I did have the correct formula I still don’t have a scientific scale so it wouldn’t work out too well.

would the ratio for red lead min Pb3O4 be 3moles of Pb3O4 and 2 moles of Al. bud

are there any two wires which you can twist together to act like a fuse say aluminum and another metal, im sure i have heard of something like it i think its called a thermite fuse

[Gilded]

Hmm... Only ni-chrome comes to mind, but I'm not sure if it can act as a regular fuse (good for electrical ignition though).

[boris_73]

i dont think it is this one you light like a normal fuse and it gives a reaction like thermite sparks fly of ect

[Silencer]

Would fulminated mercury work to ignite it? If so you can buy those things they use to ignite model rockets for really cheap and hook them up to a 9v battery or kictchen timer.

[Gilded]

"i dont think it is this one you light like a normal fuse and it gives a reaction like thermite sparks fly of ect"

 

Hmm... Perhaps aluminum wire coated with iron oxide?

[boris_73]

the fuse is just a general fuse well an exotic fuse it can be used to ignite most things i only put it in the thermite section because it uses metals and is supposse to react like thermite

[boris_73]

actualy i wounder if that would work i dont think that is it but i wounder if that would actually work all i need now is iron oxide anybody know how to get it, one method i have heard is to burn steel wool in a tube that is ment to produce iron oxide
