Big thermite reactions (manganese oxide MnO, copper oxide Cu

[plrokster309]

I really liked the magnese oxide explosion >:)

[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?

[Caswalle]

so the best thermite is CuO

[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

[TheCrazyFinn]

Isn't it MnO2?

[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??

[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 :)

[alleyezon50cent]

can i use MnO2 instead of MnO?

[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

[alleyezon50cent]

ok i just wanted it for the reaction(:

[beetmash]

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

[gevar234]

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

[darksideofthebrick13]

@gevar234 its a little worse

[beetmash]

@gevar234 i believe nothing would happen :)

[beetmash]

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

[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

[antiswattt2]

manganese oxide and manganese dioxide? theres MnO2 in batteries (:< so i can just mix MnO2 with CuO to get a thermite like reaction? o.o can you tell me what ratios? q:

[supressor2]

well, it seems to me that you are not that qualified in the point of thermite, so i would advice you to ask your chemstry teatcher wether you can give a report about thermite in your class with a experiment, that would lead to the product that u understand what is happening and why, by the way CuO and MnO2 wont reackt in that way, and fourther more you also would have a save possebillety for this nice experiment.

ps: try Ironoxide thermite first Fe2O3 : Al -> 3:1 have fun

sry for my lenguage

[antiswattt2]

:/ not qualified.. why are others more qualified than me? because i thought that dioxide and oxide would react? -.- ATM im making tatp

[Malaachi]

Thats a scary thought...you making tatp -.-"

[antiswattt2]

lol why is that a scary thought (: because you never had luck doing it?

[starshock01]

no...just knowing that someone out there who is not a licensed chemist is making a VERY strong peroxide...now that is a scary thought...

[antiswattt2]

at least i know something about it (;

[starshock01]

lol but did you know manganese dioxide is shock sensitive? just trying to light it might set it off in a thermite mixture causing an explosion

[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:

[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 .

[antiswattt2]

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

[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)

[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^^

[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

[snfx93]

i used a very small amount of MnO2 with aluminum and the reaction was quite violent and quick. Almost burned my deck XD

[flashOFmetal]

nice....do anyone know where to find CuO, Fe2O3 and alluminium oxide?

[neddy17]

your best bet is a pottery store!

[flashOFmetal]

thx !

[CarnalDiafragma]

What would you use aluminium oxide for? It works a lot better with aluminium powder lol

[PeriodicElements]

Where is the Al2O3? If yiu mean rust, it's Fe2O3...

[PyroChemicals]

Yes. Burn some aluminum foil :P.

[PS2djX]

oh , is cool , is strong !

MnO2 + Al ?

[Basco36]

Mno2 didn't work for me.

[iman10000]

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.

[iman10000]

intriguing, I'll have to keep that in mind, thanks =)

[boneleg]

The smoke cloud from the second test looks more like a CuO/Al thermite cloud. Its usually that orange color rather than the gray color of the first test. Are you sure?

[iman10000]

When I did my MnO2 thermite, it was a rather orange/brown cloud

[boneleg]

Well if the first one is CuO thermite, its is not mixed in the right proportions. Too slow.

[stoffel123]

boneleg is correct, it really looks like you mixed sth up.. the second one has the typical orange greenish cloud and the speed it should have.. the first is way too slow and the color doesnt match. also ive once lit a 100g batch of manganese dioxide thermite and it was fairly slow, while the copper oxide reacted pretty fast with the same Al.

[PeriodicElements]

No, they are mixed up. THe colour of the smoke tells the story. CuO thermite makes orange coloured smoke... DID IT MYSELF TODAY!!!

[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)

[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!!!!

[roksr4k4]

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

[superhornet59]

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

[kinggorrilla]

possibly, but MnO2 with Aluminum powder just reacts really violently.

[Charlie4778]

i thought the MnO2 thermite was the best

[bountykokos]

COOL :D
