Well the aluminium will melt at about 630°C the Gallium will still be a liquid and is about twice as dense as the aluminium so It'll sink to the bottom of the crucible. You could then pour off most of the alumiunium I guess. The remaining gallium/aluminium alloy could be seperated by adding water - aluminium will oxidise and the alloy will liquify as the gallium percentage rises. A few more steps will get you purer alloy but you're going to need some more advanced methods to get it back to semiconductor purity. As for the alumina (aluminium oxide), you can electrolyse it to get the Aluminium back if you like.
Yes, that is exactly what happened because aluminium oxidizes pretty fast. A bit oh Hydrochloric acid or scraping on the surface below the gallium would have solved that.
NileRed has a good video covering this. You can get some good reactions simply by scratching the aluminum after the gallium is placed on top of it. A good scraping of the surface will do more good than drilling into it, more exposed surface area for the two to interact.
**^^^THIS guy gets it! I had to scroll down a long way to find a comment about the ability of Gallium/aluminum alloys to generate hydrogen and oxygen from liquid water. This point touches on another "issue" he had early on in the video when initially trying to get the gallium to "sink in".** Aluminum INSTANTLY develops a protective oxide layer that prevents further oxidation, AND protects the aluminum from the gallium. As soon as you slotted it with that rotary milling tool, it was automatically re-developing its oxide layer. So, you must pour the gallium into the slot, and then push a scraper or screwdriver through the liquid gallium puddle, and scrape the aluminum underneath, in order to remove the thin, new oxide layer, which would've allowed the gallium to "seep in". Once the gallium alloys with the aluminum, it prevents the aluminum from developing its protective oxide layer, which is why GaAl alloys will easily react with water, to produce hydrogen. The aluminum will disintegrate at that point, but since gallium doesn't react with water, it'll still be there at the bottom of the water container.
You are overheating your aluminum so much! Proper pouring temperature shouldn't even glow red. When you heat the aluminum up that high it is molten for much longer and dissolves a lot more hydrogen from the air. This all comes out as it solidifies and causes bad porosity in the metal
aluminum oxide was your problem, groove, pour the gallium , then scratch the whole groove to get rid of the oxide layer.. just drilling only exposed a small amount to the gallium, but it did the job
I don’t know if it has been said yet but the reason it didn’t work in the beginning is that gallium doesn’t like to go through the oxidization that forms on the outside of aluminum
The reason it wasn’t working at first is that aluminum makes a coating of aluminum oxide when exposed to air. Gallium doesn’t react with aluminum oxide. All you needed to do was use a nail or screwdriver to scratch the surface of the aluminum under the gallium to kickstart the reaction.
oh yeah, he might have had a mix of Aluminum Oxid eand Hydroxide since he quenched the ingot. However... he DID use a milling machine to create the groove he poured into so that "should" have removed the oxide layer.
@@marhawkman303 no, the oxide formation on aluminum is near instantaneous upon contact with air. That’s why you scratch it off under the gallium layer, to prevent oxide formation.
you should weigh the gallium before you apply it to the aluminum and then re-weigh what you can collect after it all seeps out of the aluminum to see how much stays in the ingot.
When aluminum is exposed to air it forms a layer of oxidation that protects it from the gallium. Taking something as simple as a car key and scrapping off the surface just before you pour on the gallium works like a charm.
If you re-melt the ingot it'll be fine once again. Gallium lubricates the aluminum crystal boundaries, but if you melt the result, the gallium mixes randomly and forms a "solid solution" with the aluminum, similar to how adding a small amount of tin to copper makes it stronger but less malleable. And from the looks, only a tiny bit of the gallium is actually still in the aluminum. (One way to get insight, you can google image search for: aluminum gallium phase diagram, and look at the aluminum-rich side, and you'll see up to about a 5% molar ratio it remains in the FCC A1 form, or you can try it yourself like I did!)
sitting on top didn't work because the aluminum had a protective aluminum oxide layer. drilling the holes which then had gallium go directly in to the material without the presence of oxygen allowed it to penetrate due to the lack of that protective oxide layer
i wonder what will happen if you smelted this aluminum gallum ingot. since the boiling temperature of gallium is way lower than aluminum will it just separate them and turn this ingot back to a strong normal aluminum
Try this: Gallium vs. video camera. How long will the camera record, until the aluminum casing (housing) gets eaten away? The circuits would get fried too.
I saw this video first when looking for gallium videos not knowing what gallium did, but when the other video said gallium was corrosive to aluminum I was like OhhHHhh and clicked back onto this video
theese videos are bloody awsome, I can relate to this Ben, I work in a foundry which also cast alsorts of different metals, gun metal,ally,Ab2,lm4,lm25,lm6 the list goes on haha, what you do with the top and bottom is what I do well I did for a year I got 100s of pictures on my phone having to remember there's so many pattens but yeh it's intresting for sure 👏👌
it's now an ally. the reason the bar split is because the alloy changed the crystalline structure of the metal... in one specific area, not the whole bar.
Do you think you could do a step by step guide with every details and how-to of his you made the Nintendo controller supports in aluminum in your last video?
Could you put these degraded aluminium into water? I'm interested how much galium has ben still trapped at this aluminium bar, and how much of galium can be recycled :)
what would happen if you simply try to aloy galionm with aluminium? would galion just create a lot of dross on aluminium surface? or would it just evaporate and poison everything around?
Put it in water so we can see the reaction. Which would be violent due to the gallium allowing the aluminum to be permanently exposed to water. And water sets exposed aluminum on fire.
You should totally do a casting of the kill la kill scissor blade in brass, spray painted red then for the edge of the blade is the brass showing through

Thx
honestly tho why do channels do this "oh you wanted to see title name? too bad you see that after hours of lecture."
Thank you
Try and mix Gallium and Aluminum together when in liquefied form then pour in the Ingot to hard.. lets see those results
I think that wouldn't mix
You would probably have to mix alot but it would get harder to mix also the gallium would not set for ages
@@legit_jebus8607 i think would boil off because of the molten aluminum
I could but it might not be hot enough
@@yes____ The melting point of aluminum is not even close to the boiling point of gallium
What hapen if you melt again that aluminium??
yaa that what I thought too
Ah lol I asked the same w/o coment diving
I am also curious about this, I hope he does it
An alloy

It’s probable the freshly poured aluminium oxydized, and created a protective layer
Making it difficult for the gallium to interact with the ingot.
True story
Yes, that is exactly what happened because aluminium oxidizes pretty fast. A bit oh Hydrochloric acid or scraping on the surface below the gallium would have solved that.
Oxidized not oxydized
“this wasn’t something i expected” you knew fully well thats what would happen if you mixed gallium and aluminium lol
Ikr
he was expecting an even better reaction i think
NileRed has a good video covering this. You can get some good reactions simply by scratching the aluminum after the gallium is placed on top of it. A good scraping of the surface will do more good than drilling into it, more exposed surface area for the two to interact.
I like how you showed the aluminum ingots melting over time
Can you do more casting with sand videos? They are so satisfying!
I do really miss the pounding sounds AF
aluminum oxidizes so you'll have to scratch that away first, that's why it only worked when you drilled. The other indent was left out for too long.
You could've put it in water so aluminum reacts creating hydrogen gas and aluminum hydroxide, leaving the gallium intact.
**^^^THIS guy gets it! I had to scroll down a long way to find a comment about the ability of Gallium/aluminum alloys to generate hydrogen and oxygen from liquid water. This point touches on another "issue" he had early on in the video when initially trying to get the gallium to "sink in".**

Now what happens if you melt it back down?
I would like to you melt that thing,and see what happends or can you cast something with it.
PS: you do amazing work you are amazing
Put the gallium in a clear container and put a brick of aluminum vertically on top of it let's see how long it would dissolve it completely
Love the videos where you speak and walk us through what you're doing.

His goal was for the gallium to get into the aluminum and eat away at it. I'm pretty sure he did that on purpose.
But where the H2 come from? The air has only very trace amount of it.
@@tmfan3888 Moisture
@@tmfan3888 the hydrogen comes from contact with moisture in the air.
If you think he got it wrong. Post a video doing it yourself.
What happens If u pour gallium into molten aluminium?
Could you try remelting the ruined aluminum block to see if it's possible to salvage the aluminum? I would love to see if that's possible.
he'd have to do some sort of distillation to separate the Gallium from the Aluminum. But.. what WOULD it be like if he just/.. melted it?
aluminum oxide was your problem, groove, pour the gallium , then scratch the whole groove to get rid of the oxide layer.. just drilling only exposed a small amount to the gallium, but it did the job

That was cool. Plz do more experiments like this.

Hey Ben!! Try to do this.... Mix molten brass and galium and make an ingot out of it....
you should weigh the gallium before you apply it to the aluminum and then re-weigh what you can collect after it all seeps out of the aluminum to see how much stays in the ingot.
What happen when you melt gallium with alloy
When aluminum is exposed to air it forms a layer of oxidation that protects it from the gallium. Taking something as simple as a car key and scrapping off the surface just before you pour on the gallium works like a charm.
Neat. I'm glad he explained what things were that I wouldn't have understood on my own, like screwdriver and holes.
Thank you for getting back to doing your intro!!! Your videos aren't the same without those!
Can you remelt it and put the other half in the shredder
its aluminum, not some soft material
@@worldmapping4895 gallium makes aluminium soft, idiot
What would happen if you put Gallium in Molten aluminium?
Iron in minecraft was so popular they turned into a real thing 😭😭😭
you mean aluminum? or am i missing the joke
Iron in real life was so popular they made it in minecraft
What iron are you refering to , this "joke" makes no sence and is completely out of context
What happens if you stuck that aluminum+gallium ingot back in the forge?
I was thinking the same thing; or maybe you could try cleaning the gallium infiltrated aluminum somehow.
Ben you're the best and keep making amazing content

I really enjoy your channel! you are a true artist!!
The compound produced by gallium and aluminium once compounded can react with water to produce hydrogen bubbles.
sitting on top didn't work because the aluminum had a protective aluminum oxide layer. drilling the holes which then had gallium go directly in to the material without the presence of oxygen allowed it to penetrate due to the lack of that protective oxide layer
When he put the fire it sounded like a jp trex roaring
What would happen if you try to Remelt the aluminum ingot After the gallium damaged it
hey prestube if ud put the ingot with galium in water it should react and desintegrate itself leafing the gallium behind
I knew you were a Belgian instantly when you said "I'm gonna do it in this groeve" 😂 anyways nice video man 💪🏽
I got it when; i'm ben
I like you and your videos verrrryy much
U r a very polite man !!
i wonder what will happen if you smelted this aluminum gallum ingot. since the boiling temperature of gallium is way lower than aluminum will it just separate them and turn this ingot back to a strong normal aluminum
the scary thing is in just a few minutes the gallium can get absorbed into the aluminum and it becomes completely untraceable till the aluminum cracks
Does it make the aluminum change. if you melt it does it go back to a pure form or will it always be contaminated with gallium.
Try putting gallium in the furnace thing and see what it does
Luckily you don't need to put gallium in the burner because it melts in your hand!
3:17 damn the noise when he puts it in is just 👌
Can you restore the aluminium back to original state if you melt it down after it has been affected by gallium? Love your videos dude
This question needs an answer!
Can you remelt the aluminum ingots back into pure aluminum or is the aluminum permanently compromised
I feel like you're wasting a ton of gas starting the fire before the crucible is in there. There's no need to preheat the furnace.
can you put this ingot to water and enjoy
What happens if you try and re melt the ingot? Will the aluminum be good again?
Great video one question is that ingot no good now or can you recast it?
That huge cast iron ingot mold is awesome. Where could I I get one?
Nice. Ben keep making good stuff
What would happen if you add galium to molten aluminum then let it cool?
Question: What do you do with the aluminum once it is "infected" with the Gallium?
They are still researching that. Apparently the galium is recoverable and the aliminium can be used as a fuel source
yeah, the gallium and aluminum alloy will react with the water to form aluminum hydroxide, Hydrogen, and gallium metal
Re melt the ingot we need to see how it turns out
What happen if you put liquid gallium into molten aluminium and make ingot from this?
You should brass cast anchor those videos were really good
Can you turn it back into aluminum and gallium somehow?
Great channel and great man
Would have been interesting to see what would happen if you remelt it after if it would regain its strength
nice gastly pfp
You should try a circular shaped foundry, saves you lots of fuel and energy.
Try this: Gallium vs. video camera. How long will the camera record, until the aluminum casing (housing) gets eaten away? The circuits would get fried too.

As a flatbed trucker driver, we have totally different ideas of "big" aluminum ingots, lmao.

Once the amalgam is created, can you get back to pure aluminium again?
I would find it interesting to see this process again but at the microscopic level.
Most people get behind big Aluminium, but it's always good to support local businesses.

Can you do this with Mercury instead of gallium?
wonder how it will turn out if you re melt and cast the gallium alminum
Can you melt aluminium destroyed by Galium to make it useful?
I wonder what would happen on a freshly poured hot ingot.
is the aluminum ruined now? could it be remelted?
Dont you have to keep the galium molten for this to work. How did you keep the galium liquid for 2 days.
I liked before watching, I love these gallium videos you see on yt but with a huge ingot just awesome
What will haooen if u add gallium to aluminum when u r melting it. Will the aluminum hold its shape well after casting or will it turn papery
What if you pulverize that block and try to make thermite out of it?
I was so certain you were gonna rip it apart
