Aluminum powder reacting with plaster powder

From my local drugstore (specialist for paints)
I had some aluminum powder left.

When U mix it together with plaster powder
the aluminum can react with it.
But it needs a high temperature to ignite it.
Here I used a sparkler as a fuse.

I placed the mixture in a tin-can of peanuts.

WOW. Really a bright light,
overmodulating my camera.

This reaction produces an enormous heat,
melting the tin-can into an irregular shaped
piece of junk.
Residual aluminum or plaster cannot be found
after the reaction. The only thing is a slight
odour of rotten eggs
(H2S - hydrogen sulfide).

Heres the formula of it:

204 grams of plaster
108 grams of Aluminum powder

so is it plaster of paris

@DeViL12351

yap :)

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.

thermite :D

@mrkanker1

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

@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.

@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

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

[desinfector]

I think this would b too expensive
