Aluminum powder reacting with plaster powder

[DeViL12351]

so is it plaster of paris

[desinfector]

@DeViL12351

yap :)

[desinfector]

Its calciumsulfate (semihydrate)

I put this up to show that it's not necessary to heat the plaster up to get rid of crystal water.

but ...yup carbonate will do it as well but not that hot.

[Agentoxedo07]

Holy-Terrorist:>*=* The melange of calcium carbonate and aluminium reaction with hot ignition ?

[mrkanker1]

thermite :D

[desinfector]

@mrkanker1

Yup, its nearly hot like that, but its rather Thermate than thermite (no iron oxide reaction)

[Mrgeophysical]

mh...  good idea... How many gramms were that ?

[desinfector]

204 grams of plaster

108 grams of Aluminum powder

[snowyseb]

is there any place u could get small amounts of aluminum powder?

[desinfector]

dunno for down under, but in Germany in several online-shops.

even in a local shop for paints (a private owner, not a huge company) can order it for You here.

I think it should b the same in Your country.

If not, You can still create your own powder by filing it from a larger piece of Al.

[desinfector]

I think this would b too expensive

[montey1017]

@snowyseb there is an industrial chemical supply near my house, they sell thermite, pre mixed. about 5 to 8 dollars a pound (it changes) but you have to have "an industrial use permit" to buy it, but aluminum powder is about 4.50 (again it changes) and they dont sell rust (iron oxide) but if you go to a break shop, or machine shop, you can get (for free) iron shavings, and just let them sit. also you can get a railroad spike, a jar, and a transformer. fill the jar with salt water, plug in the

[montey1017]

@montey1017 transformer, put both wires in the water, and connect the end that bubbles to the spike, and let the other side sit. leave overnite. scrape the rust off the spike.

[MrSumguy08]

howd u make that

[desinfector]

I just mixed aluminum powder with plaster powder

(simple plaster used for filling spaces between drywall panels or treating a broken bone)

ignite with a toy sparkler, thats it.

[Naturepheonix]

hay you said it was hard to ignite it.

is it possible to use the DIY pull ring grenade method to make this?

[desinfector]

jup, if you can ignite electrc sparklers with that method, why not?

my suggestion for this is:

get this grey substance of sparklers powdered and mix it to the heads of matches.

But I havent tried it yet

[Naturepheonix]

oh thanks :)

[BerkinGG]

What type of plaster powder did you use? Plaster of Paris? Lime Plaster? Cement Plaster?

[desinfector]

White plaster of Paris.

Dont use and other mixtures with sand, cement

or so things like that

[chemoxid]

paris plaster ?

you mean CaSO4?

=O

amazing video

=)

[desinfector]

not just CaSO4.

This is CaSO4*0.5H2O here

Its the semihydrate.

[chemoxid]

ohh! of course

i made a proyect about CaSO4 production at school..i guess i forgot it

thanks

[cathal6606]

i have 1 kg of 250 mesh aluminum powder that i got on ebay. i tried to use it in thermite but it didnt work.

Does anybody know of anything cool to do with aluminum powder?

[desinfector]

My powder was 63 µm

U can ignite your stuff eg with electric sparklers.

[dvdavidvgt]

mix with potassium perchlorate

[maxyevs]

hmm interesting i guess calcium sulfate does give off oxygen- and this reaction is as energetic as thermite

8Al(s) + 3CaSO4(s) = 4Al2O3(s) + 3CaS(s) + 3850.12kJ

[desinfector]

umm yes i didnt know the "energetic output", thx for calculating.

Indeed it becomes veeery hot and in a cold night (e.g. new years eve) u can feel the heat when beeing 5 mtrs away.

Ive made some other vids where im explaining how to mix it.

[antiswattt]

hmmmm plaster powder? does it mean... just normal plasters or that thing,,, like just take a plaster and then ... how to i get plaster powder?! plz reply

[desinfector]

Do U know the white Plaster to be used for

repairing a hole in a wall or for mounting a

mains socket or switch?

I took this type of plaster (this is already a fine powder)

Its usually the cheapest plaster U can get in any hardware store.

Pure Plaster and no (!) ready

mixture, eg. with additives against shrinking.

U can mix this with aluminum and U'll have a flare...

have phun!

[BackyardSkunkworks]

Drywall/sheetrock "mud" is basically the same thing, calcium sulfate. You can technically just use strips of aluminum foil and drywall finishing compound, although the reaction won't be as vigerous.

[PostTheMissing]

The product is titanium right?

[TopGunMan]

Haha. nice.

unless your serious...dear god

[PostTheMissing]

Im serious.

There was an article in popular science. It was a 5 minute project, Aluminum Powder and Plaster Powder, to make titanium.

[TopGunMan]

no i read that article too. It was Titanium dioxide and aluminum reaction. Not iron oxide and aluminum...

[TopGunMan]

woops i mean aluminum and plaster

[desinfector]

No, this article u have read must be a fake.

In Plaster theres no Titanium. Theres just Calcium, Sulfur and Oxigen - when it is the anhydride. The powder I used had some crystal water as well. so theres Hydrogen in the molecule, too.

[abudabit]

Unless it's a nuclear reaction there isn't going to be an element created. Unless titanium is used in the reaction there will be no titanium by product. This is a chemical reaction, not a nuclear one (obviously).

[96bikerider96]

whats plaster powder? is it like the plaster when u brake a leg and they rap it around the leg? plz answer!!!

[desinfector]

Hi.

Yes thats what u need.

Plaster (some say gypsum) CaSO4 * 1/2 H2O

[ToolshedEd3TF]

Would you be willing to post a how to video with measurements and a step by step process on how to do this? After all this is cool as hell, but i want to make sure I buy the correct ingredients and have them proportioned correctly.

[desinfector]

Look@ "more Videos from desinfector"

There u will find my new "Thermite" Video.

Here U can see how

simple it is to set up the Mixture. No special

tools e.g. for mixing needed. OK, the ingredients have been

scaled before, but this was just to shorten

the Video. I got messages asking me this beeing a fake or not.

Well, I can tell U (and everyone elso out there):

This is no fake.

[hokalol]

hmm will it work with KNO3?

[desinfector]

Sure. But ull have a single big flash then.

[TopGunMan]

thats exactly what i wanted to know. Thanks! Know of any other easy to obtain oxidizers?

[desinfector]

mayb CaCO3, but i didnt use it yet.

plaster is already delivered as a fine powder and it works well. So i dont look for other stuff.

[pyromodder]

CaCO3 and other carbonates work as oxidizers. Glutamates, citrates, nitrites, phosphates, gluconates, cucrates, stearate - many of these compounds can be used with a strong reducer such as magnesium.

[TopGunMan]

wait... plaster poweder is an oxydizer???? how!?

[desinfector]

Ca-S-O4

see the O4?

Aluminum takes any oxygen it can get.

And... try this using Magnesium. ull be amazed!

of course this "oxidizer" cannot ba compared to nitrates or chlorates, but it works.

[MDHmodder]

it's stronger than nitrates at a high tempature. If you se the right ratios this will burn up in a bright flash instead of a flare.

[rhyslightning69]

do u mean THAT if i crush up a plaster board i can use that ?

[desinfector]

"fresh" plaster powder is cheap enough...

:-D

[AlexiLaiho227]

wow, i didn't now that plaster could react with anything, it seems like such a dull substance.

[desinfector]

YES...

Tee the Formula of plaster, 4 times Oxygen in

the sulfate. So Aluminum can react with it as

well.

The smaller the grain size of alu, the better

the reaction runs through. Here I had some 63µm grain size of Aluminum.

And heating up the plaster in order to get rid

of the hydrate in the molecule, the reaction

is even more intense.

Residual stuff left by this reaction smells a bit like rotten eggs (H2S), but not too strong.

[desinfector]

Heres the formula of it:

204 grams of plaster

108 grams of Aluminum powder

or

102 plaster

54 aluminum

... and so on.

U can use it as a starter for thermite-like

reactions if u have any trouble to ignite.

[halflifeh]

is this the same heat as the other thermite or less? thanks

[desinfector]

Well I cant measure it...

I have no pyrometer or so.

But yes its still some heat U can feel when beeing 5 meters away.

[burnthehypocrytes]

Will this work if i use home made aluminum powder, and what is the mix ratio?

[desinfector]

It can work with "homebrew" aluminum powder or even larger chips up to 1mm grain size. But igniting a mixture of chips only will often fail. use a mixture of fine aluminum powder with plaster to ignite mixtures with lager aluminum chippings.

U can (so to say) fade it over to the other mixture. Dont create any zoned laminations in the setup. The reaction will stop without burning the larger chips.

[chr1s510]

so where do you get aluminum powder?

[desinfector]

U can get alu powder in stores carrying paints.

Some shops offer a mixing service where u can

get a unique mixture. Therefor as pigment color-powders are used as well as liquid pigments. U should also be able to contact any manufacturer of paints. And last but not least ebay...

[desinfector]

This is not really suitable for rocket-fuel.

To boost a rocket the exhausts have to be

gaseous media. Here the state of matter is

solid. That means that just dust and smoke is created

by this reaction. The stuff does not expand like

real rocket-fuel.

[manvstaco]

can you use this as a rocket fuel??

[cocopuff696969]

make a vid on how to make it

[desinfector]

[Quote]quick-setting gypsum plaster consisting of a

fine, white powder,

calcium sulfate hemihydrate, CaSO4 * 1/2 H2O

which hardens when moistened and allowed to

dry. Plaster of paris is prepared by heating

calcium sulfate dihydrate, or gypsum, to

120°--180° C (248°--356° F). With an additive to

retard the set, it is called wall, or

hard-wall, plaster.[/Quote]

So I mean the simpliest plaster e.G. to mount a wall socket into a brick-wall.

[oishi222]

wait, plaster of paris???

i got a shitload of that in the closet =)

[desinfector]

Use aluminum (here 63µm grain size) and plaster.

U'll save a shitload of money on pyrotechnics!!!

No fake. No special oxidizers

like nitrates or chlorates!!!

+++ No forbidden stuff! +++

Plaster will always be available at your drug store or home-depot.

Dont look into it directly. It's realy damn brite!
