So in this video I’ll talk about a very interesting metal - bismuth. Bismuth is a heavy metal and in the periodic table of chemical elements is located next to the Lead.
Bismuth is a shiny and very brittle metal. I bought bismuth in these sticks which are very easy to break if you slightly hit them with a hammer.
The breaking point shows that bismuth rod has a very clear crystal structure. Now I will melt it to show you one interesting property of bismuth.
Bismuth’s melting point is 271 degrees Celsius, so it can even be melted on a hot plate. And unlike lead, bismuth is not toxic.
Bismuth’s surprising property is that it starts to form beautiful crystals during solidification. The size and shape of the crystals will be dependent on the solidification rate, as well as the presence of impurities.
My bismuth’s purity is only 97.2%, so turning it into large crystals will be problematic. Once bismuth is melted, I turn the hot plate off and wait until the bismuth will gradually harden.
Bismuth’s solidification rate can be reduced by heating in a sand bath or by using a thick-walled container. The slower the cooling, the higher and more beautiful crystals will be obtained.
Furthermore, you need to make sure to remove the cover from the crystals in time, which is formed on the top of solidifying metal. At some point later, around the time when a third of bismuth is crystallised you would need to drain the liquid metal to expose the beautiful crystals.
To avoid burns and injuries, do not repeat this experiment!
If this was a pure bismuth, the hot crystals on air would have begun to cover with a beautiful oxide film.
However, my bismuth has a lot of lead impurities and on air the film of oxides does not form. To make the crystals colorful I'll apply a current of pure oxygen on our hot crystals.
I get the oxygen from the decomposition reaction of hydrogen peroxide. When bismuth contacts pure hot oxygen, it is covered with colored patterns caused by the oxide film on the metal surface.
Once the cup with crystals is cooled, those can be removed. The crystals obtained are not very big, however with a beautiful oxide film.
I made several attempts to grow larger crystals, but every time I got only polycrystalline aggregates of small bismuth crystals.
I think the problem is in the impurities. As it is known, the purer the material, the more beautiful and larger the crystals are obtained.
Bismuth and its compounds have many uses.
It is used as a component of some alloys, aldo bismuth oxide is used in organic synthesis and in medicine as a remedy for gastrointestinal diseases, other bismuth compounds are used in nuclear power engineering, electrical engineering as well as for the creation of magnetic materials and superconductors.

Those are not crystals, they are the apartment blocks that the Bismuthians live in.

i AM LITERALLY DYING RIGHT NOW
REALLY
we're melting them down into different shapes for fun
I play Trove, they got this weird Bismuth dragon, maybe it lives within.

I always think of bismuth crystals when people tell me there are no 90 degree angles in nature.
Pyrite does the same... very nice and exactly 90 degrees
Don't forget galena and fools' gold.
Theres a lot of cubic crystals such as regular table salts and galena. Theyre all relatively 90 degrees and happen naturally. Natural bismuth crystals arent usually common and most crystals are artificial (aka someone had to heat it themselves).
@@medexamtoolsdotcom pyrite and fools gold are the same thing
Not quite 90, as they tend to spiral. That's my experience, anyway. I'm not saying that 90 degree angles don't occur in nature, however.
I love the square shape of the crystals.
You can easily get high purity bismuth in small quantities from Rotometals. They have 99.99% pure bismuth. It comes in chunks that are broken off of a larger slab. I bought 1lb of this bismuth several years ago, from another source, but I'm pretty sure they got it from Rotometals. Rotometals sells on Amazon and on their own site, but I'll point out that when I was shopping for gallium and indium a few months ago, I found a sale from Rotometals on Amazon, and they had a significantly better price for 100g at Amazon than on their own website at that time. So it's probably best to look on Amazon and maybe even ebay for rotometals' sales, just to make sure you get the best deal. Or call/email someone at Rotometals to see if they will match their own Amazon sale price if you buy direct.
dude thanks, i'll look into these guys
DID U BUY ANTIMONY?
I WANT TO SLEEP ON A BED MADE OF YOUR ACCENT
it is sooo normal to have accent if your native language not english
english have accents too lol, everyone speaks differently
A pity for you, the bed turns out to be made out of hard keramic. Not ceramic. Keramic.
I love learning about various elements from this channel.
Phenomenal series - learned more from Thoisoi about metal elements than over 60 years of education.
Bismut crystal is so beautiful :)
The Bismuth is beautiful...
Loved the cat!!
Now I like even more your channel.
ビスマスの結晶、綺麗ですよね！！

thank you for such amazing videos...
I'm a chemical engineering student(sorta)
most of the materials I study about...I haven't seen them in action...
so thank you for such educational and Amazing videos
awesome channel dude keep up the great work
this is very informative
I saw your Snickers and Potassium video. I found it pretty fascinating.
very nice work
second. Thoisoi, your videos are amazing! Thank you. I improved my chemistry knowledge)
perfect 90-grade corners
Those crystals are perfect! :O
Could you please do a video on crystal lattice invasion again?! Great video!
Thank you!
Poor Bismuth, it's surrounded by dangerous elements. (Polonium, and Lead)
POOR BISMUTH:(
From certain sources I hear bismuth is as rare as silver but I believe it’s not considered a precious metal because of its properties, precious metals aren’t precious solely because of being rare compared to common metals extraction rates, but also because there amazing properties. Precious metals are highly resistant to corrosion even when heated to melting points, bismuth is resistant to corrosion in air and water but easily corrodes when heated, the corrosion is the many colors it produces. Also it’s very brittle. Gold is soft and malleable but it’s not brittle and easily breakable, also gold never corrodes outside laboratory conditions, in air or heated
I have a couple questions. You take the top layer off to avoid oxidation right? Could you make a better crystal with an airtight argon chamber?
where can one buy supplies to combine to do such experiments as well as getting other metals?
good Jobs. saludos desde Argentina....
I love your channel mate, hope this comment helps you!
Your channel is best 👍👍
Good thing about this is if you fuck up you can just melt it again and start over
Like Water, Bismuth also expands when it freezes. I saw that in the video.
So this is the metal thar metalheads must love?
Bismuth, used in low-temperature solder. Like in very heat-sensitive equipment, or old (computer) mainframes.
hi Can you tell me where do you buy all of your metal ?
Works great in Orgonite manufacturing too :)
make a playlist of eliminates :)
Small but beautiful crystals.
I found that bisthmuth is also able to be spectrometerly inconsistent. One assay claimed 89% Ir 10% Pt .8% Au. And .2%Pb and with your Iridium video, I turned the surface area Of a 1lb 8oz Ingot Into a powder. I did another spectrometer assay at another location and recieved the result of bisthmuth. With the fine powder I had done what you have shown with Ir and sprinkled the powder over a torch flame. The result was precisely as visual as Iridium powder. The Ingot before fire assay shown green spots on the base which was intresting due to reading Iridiums hydrolysis is substantial, Possibly making the combination of Ir, Pb, Au, Pt, Bi the effective vessel for a half life distribution morphology needed to allow the the efficient method of turning lead, into Gold?
that would be cool to mount in a ring.
Funny to see those 90 degrees corners.
Bismuth produces some of the most beautiful crystals i have ever seen.
Very nice Mitra
Can you wash the left overs in the sauce pan?
There is a possible experiment one can do with bismuth by creating nanoparticle bismuth filings and use it to show radial electric field lines surrounding the wire, much like how iron filings are used to show circular magnetic field lines surrounding the wire.
Is this actually doable? Maybe it is the lack of purity in my bismuth samples, but the chunks I have do not really interact much with magnetic fields.
It's hard to imagine that a difference of 1 electron, 1 proton and 1 neutron can change a boring looking metal Lead to such a cool, colorful and geometrically intriguing Bismuth.
Why is lead boring? It has colorful oxides and some even taste sweet! Its also one of the first and most widely used metals by humanity. Lead is my favorite metal, its in my favorite flux core solder, its in my favorite electronics, it enabled the printing press etc.
why are we not using this for circuits structures?
fascinating
nice cryshtalz you got
... and unlike lead, bismuth is non toxic.
... my bismuth contains many lead impurities.
I luv this guy!
Where I can buy really pure bismuth?
That's epic.
NurdRage would probably know how to purify your bismuth ;)
Cody's Lab
I think they both would know :D
GiggitySam Entz you either create a solution and draw out using electrolysis or you allow a very slow cool down time, and cut off the biggest best shaoed crystals then repeat the process 1 or 2 more times
or NileRed :)
Üzerinde çalışmayı deneyeceğim, olayı çözeceğim
Bismuth is my favorite element in the table.
Some Random Person agreed! So sad that this comment got burried, THIS COMMENT NEEDS MORE ATTENTION!!!
mine too... I just saw a guy making a knife of it and soaking the handle in bismuth at the end to grow cristals with the help of the thermic shock (cold bismuth soaked in close to solidify bismuth)... very nice but impossible to hold in hand lol...
Awesome cool
That's bismuth as usual. Sirius bismuth!
Bismuth has a negative thermal expansion coefficient, means it contracts when heated, you can show that also....
Came for the experiments.
Stayed for the sexy voice.
How much does bismuth metal cost? And would it be a good project to do at school?
"and wait until Beastmode hardens" :D.
he deserve all crazyrussianhacker's subscribers ,..i think 😒
wellcawm tew mii laboruhtoree wair sayftii is numbur wan purrorti
ouhh mieeann look ath those beeutifhul kreeshtalz
Certainly more than crazyrussianhacker deserves them. Thunderf00t showed how awful crazyrussianhacker is.
Does it grow infinite bismuth then?
how do the crystals get perfect looking angles ? it looks manmade ! i love it. But really how the perfect looking 90s ?
because it has a cubic crystaline structure like table salt (NaCl) because of the external electron layers that rule how each atoms are bonding together...
I love his accent xD
Are Karambit Fades also made of Bismuth?
Tom H. Yes and Case Hardened knives are made of 1000°C glowing knives
How to buy
nice vid, but you could have mentioned the radio activity.
EDUARDO SANCHEZ
iceberg789 It's so weakly radioactive that it's still considered stable by most chemists.
Brett Davis
so, no cancer/radio poisoning from accidental consumption ?
iceberg789 It has a half life of 19 quadrillion years, which is more than a _billion times_ longer than the age of the universe (13.8 billion years). So yeah, you're safe from radiation poisoning. Haha.
i see.
99% Other
1% Steven Universe
i love science
Bismuth crystals are beautiful
my favorate metals are rubidumand bismuth
You sound like great Scott
What about Gallium?
How much is bismuth
Will 100gr of bismuth be enough to make crystals?
Nope min.500 Gr.
I like Bi
U Wot M8 mee too
Best element
Rad, but why are the crystals square? Should'nt they be hexagons, or octagons or something
Different compounds have different crystal shapes based on electron bonds. Carbon has many. Take some allotropes of carbon for example: diamond, graphite, lonsdaleite, fullerenes (C60, C540, C70) amorphous carbon and carbon nanotubes.
were did you get this stuff?
The Internet
It's actually not that expensive
ONLINE SHOPPING
Whenever i think bismuth i think steven universe bismuth
intresting
i like bismuth are beautiful and super rare
☭_DRINK_CCCP_420_☭ hey, have some respect with the dude, just because he likes that shitty games doesnt make you superior or something like that
0:00 kheylo e'e'r'un. It's weird, he didn't quite get a single consonant right, and yet I knew what he said.
Bismuth is also radioactive, though very weakly, sufficently to allow it to be safe for almost all if not all purposes.
Everything is radioactive. Just saying.
DarkHawk 317 Bismuth has a half life of like, what, 19 quadrillion years? Yeah I'd say it's safe to handle :P
***** Now that I look back at this, I forgot to tell you that it's almost impossible to find any "stable" atoms, well most stable I can think of is inert gasses, which are quite rare anyway.
>Any time soon.
Nothing lasts forever just fyi.
Just because something has halflife longer than your own life doesn't mean it's not in fact "radioactive".
How can Bismuth crystals have square shapes?
+Bonus Cat!
How much did that amount of bismuth cost??? I absolutely love bismuth! Also, can you re-melt the crystals and make them again? Somebody reply i need this information, thanks!
EnderGuard1 Yes you can melt it again and again if you want.
25$ kg from ebay
so this is Bismuth's history from Steven universe
Fader yep lol
yep
TheLuckCraft oh yea can u sub me
Fader sure why not ;)
yay I'll do the sams
Isn't bismuth radioactive?
It look like it could form natural circuitboards.
🔥🔥
add cat to video instant win
the cat play with CuSO4?!
Before become obsessed with shattering diamonds.
what's the deal with Russians and bismuth crystals?
Why bismuth become those square blocks
Itsa me Mario 👌🏿
It's melting point is 271° Celsius??? That's pretty HOT 🔥
Mix it with tin and you can get it as low as 127c!
