Gallium Reaction With Aluminium And Gallium Recovery

Here is a very interesting reaction between gallium and aluminium.

Would there be a good way to remove the aluminum oxide? Maybe a sieve that the gallium won't stuck to, then boil off the water? This might be a more repeatable process that could be automated.

Good day man, thanks for the video, I knew Galium letches into aluminum, however I never knew it is so simple to extract again...

One question, I also know Mercury does the same thing with Aluminum, would you recover the mercury using the same method as to recover the Galium?

I recently did an amalgamation of gallium-alumium-indium for viscosity experimentations, after reacting the alloy with h2o presumably reacting off the aluminium. I was then left with a liquid alloy bi-product which I assumed to be the remaining gallium and indium. The bi-product alloy remains in a liquid/jelly like state in the h2o with no visible reaction once the aluminium is reacted away.

when i attempted to retrieve and recycle the remaining gallium-indium alloy it rapidly oxidized as soon as dried and exposed to air. This oxidation of the bi-product was quite exothermic and resulted in a liquid blob with an oxidation layer. Each time i disrupt the oxidation layer and expose more liquid alloy it rapidly oxidises and continues the oxidation reaction until the entire liquid alloy is oxidised into powder.

My question is why has my gallium-indium biproduct become so reactive in air that is unable to be recycled or handled when a standard indium-gallium alloy wouldn't react the same?

*Edit, The metals are mixed at room temperature under standard atmospheric conditions so a complete amalgamation may not be the correct term

Get this man a space heater! Cool vid 👍🏼

During the time aluminum and gallium are in the water. Is there anything that’s toxic in terms of gas released? Other then hydrogen?

Thank you for sharing this was very helpful my question is, how much gallium did you use?

[JAllenKaiser]

Did you weigh the recovered gallium to confirm how much was recovered? That end-product doesn’t look like 100% of the original starting amount used… Either some Ga is converting to gallium oxide (Ga2O3) and being lost, or some liquid gallium is adsorbing onto the aluminum oxide particles’ surfaces, and not coalescing into the liquid mass being extracted, no? …It would be interesting and extremely useful to know how to recover 100% of the gallium, that way it *could* actually be used indefinitely in repeated cycles of Al-H2O reactions. …If there’s some Gallium loss each cycle, the reaction can only be repeated a finite number of times.

Please entertain this very weird question🙌
If you pass direct sunlight through that liquid can someone be allergic to the light once it's passed through the liquid?💨

[sschevelle]

can you crystallize the aluminum back to solid by melting it

[doggygaming]

Is there any useful purpose to this? I thought it was interesting as a way to get hydrogen gas but you would need 10, 000 plus lbs of aluminum just to heat a home for a year.

I was looking for a way to non-destructively separate the aluminum oxide. I wanted to use gallium to create aluminum oxide so I can make thermite. Every method I found on YouTube so far before this one required destroying the aluminum oxide. If I would have had half the mind to think about just heating it up again I would have been okay.

It's a good process to do hydrogen gas I'm testing it at home after that study published 1 year ago, but seems you was 2 year before them. But anyway most seem to use electrolysis for the H creation in industrial scale of H-steel production in Sweden but that's a waste of energy so just casually thinking of this stuff and how it can be done more efficiently. Like blocks of GA and ALU, and I want to test if ferro fluid could be used to someone fuse it with the Ga:alu to use magnets to live around maybe in half water half cyclohexane solution to handle the oxidation somehow. or use magnet driven spinning propeller inside the ga:alu solution to rotate the oxidation to keep the H production longer, but just hobby enthusiast that like to think about stuff and test if possible

Can you mix Gallium, Indium, and Tin and heat it in a beaker and keep it dry, then amalgamate it with Aluminum (while dry of course)? Then, add half of the Aluminum Galinstan amalgam to a beaker with water (H2O, Hydrogen oxide) and create Hydrogen, and the other half to a vodka (40% solution of Ethanol and Water) to create Hydrogen? To then see if they both create the same amount of Hydrogen provided there's more than enough water. I have a video where I produce Hydrogen from Galinstan and water 3 years ago, and another video where I mess up the production of ethanol water yesterday, but still managed to produce a little Hydrogen!
