I believe you got the copper thermite and manganese thermite reactions mixed up. Copper thermite is much more powerful than manganese thermite.

[RokSrakaCar]

I did a very extensive research about thermites. Copper thermite is more powerful if you have small amounts of mixture (about 5 grams). In this video, I had about 300 grams of mixtures, and in this circumstances, manganese thermite is much more powerful.

[gevar234]

What would happen if you made thermite with CuO but replaced the Al with Mg?

[supressor2]

your video has a mistake :

the first is the MnO2, and the second and strongest the CuO,

i have witnessed both in praxis and CuO is a lot mote violently than MnO2 ,

but very nice viedeo

[plrokster309]

I really liked the magnese oxide explosion >:)

[thatdudeatthepark]

@supressor2 maganese oxide(MnO2) thermite properly mixed is 4.8 kj/g or so and copper oxide(Cu2O) thermite properly mixed is 2.2 kj/g

[montey1017]

hmmmm never thought to use copper-oxide, I guess thats what im doin next time I get raw amuminum or magnesium powder

[Flamingtaint]

What did you use to ignite it?

[roksr4k4]

@boneleg I'm absolutely positively 100% certain! :D did an extensive research... btw RokSrakaCar = roksr4k4

[roksr4k4]

@Caswalle it depends on what you believe to be "the best"... if you want powerful reactions, CuO is better on smaller scale (few grams). When you do the experiment on much larger scale - hundreds of grams (like I did in this video), MnO is much more powerful...

and yes, RokSrakaCar, beetmash and roksr4k4, are all me :D

[Caswalle]

so the best thermite is CuO

[TheCrazyFinn]

Isn't it MnO2?

[dawson01912]

@beetmash

Copper oxide produces brownish cloud. Are you blind? Managanese dioxide is also slower very slow in 40g quantities.

You have them MIXED UP!!!!

[superhornet59]

@RokSrakaCar If you don't mind my asking, why?

[supressor2]

@beetmash nice 4 u in my contry i guess u cant win anythink for energetic chemestry just for the matter of the fact that people shouldn`t practise them theres no intrest in well informed pyro`s^^,

well now to the content of your message as i have witnessed several times both thermites in pracis u have a hell of fine MnO2 and bad CuO or u have mixed it up  becaus CuO thermite is used to be significat stronger ,

sry 4 my bad lenguage^^

[beetmash]

@boneleg it is mixed in right proportions! copper thermite is much faster when in low quantities... trust me! (I am RokSrakaCar, but I have a new account)

[beetmash]

@supressor2 i did a 25 page research project on thermite reactions and win the gold prize for young explorers in the field of chemistry (the only one in the entire country - Slovenia)... by the way i AM RokSrakaCar, I just have a new account (you will just have to believe me)

[beetmash]

@alleyezon50cent you could... reaction will work between Al powder and any metal oxide, you just have to mix them in correct proportions.

[beetmash]

@nickalisse manganese is more explosive in bigger quantities, like here for example, while a copper thermite is more explosive in smaller quantities (a few grams)... by the way, I am RokSrakaCar, I just have a new account :)

[beetmash]

@beetmash by the way, i am RokSrakaCar, i just have a new account :P

[beetmash]

@gevar234 i believe nothing would happen :)

[darksideofthebrick13]

@gevar234 its a little worse

[nickalisse]

Is it he copper or the maganese thermite that is the explosive one?? You say it maganese when it's using more material, but supressor2 says that you've made a mistake. So wich is what??

[alleyezon50cent]

ok i just wanted it for the reaction(:

[sulimanayad]

ya manganese dioxide can be used. in fact its the higher oxides of manganese which provide a more impressive show. the problem with the higher oxides is that they attain a temperature hot enough to vaporize the manganese... so if you're planning on retaining any of the metal it's really necessary to go with MnO

[antiswattt2]

lol Because* reaction* energetic* knowledge* chrushed?? bad luck.. how? at my first makings of tatp?

[supressor2]

becaus its seems to me that, sry, if you dont understand a "simple" thermite reaktion you might hurt yourself while making energetik experiments without knowlage. (without mention the countless fingers tatp Crashed)

also i looks like you had`t bad luck allready well i wish u luck u will need it .

[alleyezon50cent]

can i use MnO2 instead of MnO?

[antiswattt2]

manganese dioxide can burn...? just by itself.. sounds odd i have alot of it.. its in my drawers about 1 meter away ill try to see if it burns.. later ^^ but you really gotta mean manganese dioxide THERMITE.. o:
