Chemiolis: Hides face. What we see: (Safety) Glasses. Blue labcoat. Conclusion: Clone of the same stock NileRed came from. I am very good at science.

When I saw the NaOh 75% go into a flask with rocks, stirring and heating, I thought, Oh this should go well...

Your channel fills a void in my chemistry heart that no amount of solvent inhalation could. Bless you

Only in chemistry could you say "when dissolving rocks, if it won't go, take a hammer to it. That'll take care of it."

I ordered a wand from Amazon, that was filled with a Thorium powder. If you search for medical wand or whatever quack medical devices, you will find Thorium filled products from China being sold for very little, as they have no other market for the Thorium. The only reason for getting the wand was to have a source of radiation to test any radiation detectors I find.

extracting radioactive metals from rocks, this is interesting damn

That was so fuckin cool! I had no idea you could use an organic reagent to complex an inorganic salt into being soluble in a non polar solvent. I learned so much new chem from you as always thanks so much. Youve been my new favorite chem channel since i found you with just a few hundred subs!! Also as soon as you said "boiling a 75% hydroxide solution" i was like oh shit i know whats coming next XD

Next video: I built a particle accelerator to make the nuclear bomb :)

Wow I thought inorganic chemistry was just some kind of conspiracy/urban legend until i've seen this video

I want rare earth jelly on my morning toast

Awesome video as always!! Just as a side note: At 6:36 you mentioned that the residue left on the filter are various lanthanide hydroxides. In fact, it is probably only Ce(OH)4 and less to no other lanthanide elements. You've adjusted the pH to 3, which would precipitate all the cerium (IV) ions since they are more acidic, but the other trivalent lanthanides stay in the solution as sulfates. The residue is also probably contaminated with sulfate salts of lanthanides, since Ln2(SO4)3 are only slightly soluble, and NaLn(SO4)2 (from your previous addition of NaOH) is practically insoluble.

I found a piece of uranium/radium ore that gets around 10,000 CPS not CPM.. It was in a little forest near the train station in The city of Ottawa, Ontario, Canada where I live. There's much more hidden under the soil, I just took a few rocks..

Don't know why, but I'm starting to get some "The Young Poisoner's Handbook" vibes from this "rock series". 😉

One use of thorium metal is a device called a multi leaf collimator beam shaper that is used for proton and electron beam radiotherapy devices. Thorium is used because it doesn't emit many neutrons when hit by the beam, in contrast tungsten makes lots of neutrons from the beam.

Chemiolis: "it is time to extract the only other radioactive element that is significantly present in the earth's crust: thorium" Potassium: "BRUH"

Very nice video ^^ What you show during extraction and purification has a comercial name: THOREX in analogy to PUREX for extracting Uranium and Plutonium from fuel rods .

That is one hell of a complex. Wicked cool video.

That’s one hell of a stir bar awesome job cheers

Apparently, concentrated phosphoric acid at high temperature can dissolve the REE-phosphates. It would be interesting to see a video using that technique as a comparison. Loved this video!

Thorium has quite rare feature of having +4 charge while remaining stable. Most of +4 ions hydrolize very easily, but thorium can remain in not too much extreme acidic solution for a while. Which makes me think: Is it possible to catch thorium (as well as other metals) in EDTA complexes, slowly raise pH to a level when all hydrogens of EDTA are substituted, and then separate the complexes on the column with ion-exchange resin? Thorium complex should pass through while complexes of +3 and +2 metals should remain on the column.

Great video thanks for sharing

Make a video about saftey in radioactive chemestry and how you store this kind of radioactive powder, it looks scary. Do you test for contamination before leaving the lab? What detectors do you use for this?

Really nice video Where did you get TBP?

Good video on extracting thorium salts from ore. Prob how they refine it for reactors.

It is fun how lead is from something it stops amazing job great work

Can you make a video where you show all of your stir bars?

Thanks. This will be really useful for a little project i'm working on

Thorium is used mainly in the welding industry they add it to tungsten it helps to establish the ark!

watch him build a thorium reactor next vid

That Thorium complex shown a 9:00, looks crazy and almost like some sort of demon xD Do you know what the name of that complex is?

I wish I could work with this pal

funky rocks

Its also used in lantern mantles

I remember Mass Effect 1 had something about polonium and maybe thorium in the radioactive bullets ammo upgrades. Also there's the thorian enemy but presumably no relation. Yum.

I can’t understand why you don’t have more subscribers! You remind me of the Great Chemplayers

never seen TBP extraction before, thanks

If I recall correctly, the Thorium Nitrate is the stuff added to silk mesh bags to create Welsbach (von Welsbach?) type mantles for gas lnterns

Quack radioactive "health" tool manufacturer: WRITE IT DOWN WRITE IT DOWN

I have found ThO2 especially difficult to dissolve in acid. I'm kind of surprised you were able to do it here. I tried aqua regia and was only partially successful. I added a very small amount on HF (~0.1M) to my aqua regia and managed to dissolve all of it. My hypothesis is that ThO2 is similar to SiO2, glass. Glass does not dissolve in most acids, including aqua regia. This was oxude firmed a passivation layer over the thorium that was impervious to the acid. This method, however, requires the use of a Teflon beaker to mix and heat to material. Perhaps try neutralizing the acid with CaOH. This may neutralize the HF first and allow the thorium to precipitate first since all other metals will readily dissolve in aqua regia. I would be interested in seeing your results

Your tumbler ball-mill idea was a good idea, but you missed TWO critical features. You needed bigger ball bearings *_AND_* you need to add WATER or soft tumbling media inside up to the level of the media and rocks (which should have filled the tumbler container about half to 2/3rds-full). The action of a ball mill requires significant weight in the crushing media so it repeatedly falls on the rocks and chips away fragments eventually grinding them to dust, and it can only do so with the chamber at LEAST halfway full to get enough height on each subsequent revolution.... ....and it requires water to better suspend the crushing media and serve as a lubricant. Alternately, you could have just used multiple mineral specimens of similar hardness and they would bonk and grind one another to powder. Although then your thorium would have been more dilute, or you would have yielded much more depending on what other rocks you tossed in there. I have found in my experience a hardness of 7.5 is ideal for grinding minerals, garnets, corundum, chert, agates, quartz crystals and flint are ideal for grinding away minerals. What is left will be powdery fine sludge. *But the chamber needs to be at least half full and there needs to be water... SOMETHING (be it rocks or ball bearings) has to fill the chamber almost halfway to get the right mechanics inside.* The teeny balls you used would just aggrigate at the bottom and roll around while the rocks repeatedly fell on them. That is why it didnt work, the mechanics happening inside were backwards. You need the balls to fall on the rocks, and enough of them to grind and crush against each other. Even when you used bigger balls, I suspect the chamber was still too empty allowing the balls to just roll around the bottom.

Thanks for the video. Does ThO2 occur in nature?

and voila! you're on your way to putting together your very own thorium reactor. stay tuned for the reprocessing videos.

thank you for sharing your file 9:03 wow beautiful lookie like a butterfly with three finger claws

You need a microscope to see pleochroic halos in thin section

Your instructions were very clear however I am not in possession of 1.3 lbs worth. What is the best way to store this amount worth?

There’s a gemstone that’s somewhat radioactive and has a trashed crystal structure due to the radioactivity. Ekanite, I think, and I believe that it’s radioactive because of its thorium. I have one (I’m pretty sure) of a few carats. Monazite of good appearance is sometimes used as a gemstone too. Probably not too dangerous if you don’t wear the jewelry with the stone much.

There are so-called "negative ion wand/nano energy alkaline water stick" for "water activation" on various e-commerce sites from Chinese sellers. These look like regular metal pens, but are actually filled with >70% Thorium oxide powder. They cost 5-10$ per piece, and may be an economical option for people wanting to do some thorium chemistry. Never ever think about buying or opening one of these if you don't have the proper safety precautions and equipment to handle radioactive dust!

Yes, finally, an extraction of thorium, my second favourite element after cesium

Where did the daughter Nuculides go? Were they part of what you threw away? It would be interesting to track them just to see what happened. Interestingly (I'm sure you know this but others don't) - radionuclides are used to easily track where they move. For example, radioactive phosphorous to track plant phosphorous absorption, etc, or a hospital scan (most commonly with technetium).

Is the concentration of the NaOH solution by weight or w/v?

Chemiolis, I think you would greatly enjoy the Radiacode-102 scintillator.. it can perform gamma spectroscopy on samples, and is very very sensitive to gamma. Check it out!:)

Can you do a cloud chamber experiment video showing different radioactive ores in the chamber

Love it :D comming from nuclear chemistry. Especially from a departmend with a big Uranium/Thorium research background I wanted to add: that what precipitates out when adding Sodiumhydroxide to Thorium in solution is arguably better described as ThO2 × H2O. So Thoriumdioxide hydrate (same with silver) Maybe you left that in for Video purposes as most recognize a hydroxide more than an oxide hydrate. (I made that mistake of writing "Th(OH)4" once and immediately got corrected by Prof.)

Oh wow the tri-butyl phosphate thorium nitrate complex is a beautiful molecule

Anyone got the paper of the procedures he used?

Do be careful, Cody's lab got raided for doing very similar chemistry, except was extracting uranium.

this is awesome!

You need a hexagonal barrel tumbler to use as a ball mill. Otherwise the ball bearings just roll as it turns instead of tumbling.

Gonna snort that shit😂

Now I'm tempted to buy some thoriated tungsten rods. I don't even weld.

THOREX! The optimum acidity is about 3-6 M HNO3 for max Th extraction. Back-extract with 0.05 M HNO3.

Cobalt now?

Where did you do your bachelor?

I hope there's a more streamlined way for refining Thorium, as Thorium Molten Salt Reactor looks the only way fission will really take off and make a difference.

They're not rocks. THEY'RE MINERALS!!!!!!

8:58 Is that thing some final boss escaped from an ascii adventure game?

1:28 was that an electrical spark in the counter exactly when it reaches 875 cpm?

next step on Chemiolis' road - graphite - uranium nuclear pile ...

Your insolubles at 5:02 contain RaSO4. I don't suppose you have a fume hood with strong negative pressure to further isolate that terrible cation without killing yourself.

New actinocene to make... just dropped. Thorocene.

Organothorium chemistry?

“Subscribe to survive nuclear disaster” Ah yes, the kind of disaster where this chemistry is needed, to power the thorium reactors that we’ll have built… because obviously, that’s what you do in this kind of situation ;-)

I did the extraction with 250 mg Pu. Was fun.

That Thorium complex structure looks like when chemistry starts producing petroglyphs.

Thorium should be focused upon as the future of nuclear energy. Alas, it doesn't make for good weapons, so it's largely passed over for uranium. Humans continue to be the main impediment to the advancement of humans. 😢

I don't know how the rock tumbler wouldn't work except that it would probably take a week or three.

Can you extract more other rare earth elements from ores

The tumbler won't turn your rocks into diamonds, because you are not a kid. Jeez, it says it right there on the box!

Next up: making a thorium reactor and destroying the economy 😂

My thorium oxide is a bit off-white. It has a slight yellow tinge to it.

Make thorium Floride to make your thorium reactor 😉

9:00 This Complex is so fucking cursed.

Thorium dust, don't breathe this!!!!

When octapheno uranocene?

Hi i am afghan. Very very very very very very nice. I like this video

You didn't put enough material in the rock tumbler. The drum should be about 1/2 full of balls. Lot of people use rock tumblers as mini ball mills and there are a number of guides out there. You might also want to use larger balls.

Erh, rookie question, here but: having a fairly pure solution of thorium nitrate, why didn't you just electrolyse it?

Hey why don't you discover new elements

2:59 really ? why? lol! what a silly idea! 5:34 and quite a bit of Thallium...8:00 TBP oh boy.. here we go... Yeah I am not sure where you got the idea from but we should`ve talk and save glassware! cool

Don't forget thorium oxide is also used in Breaking Bad for... You know...

Chemicals didn’t end up yellow = Not Ex&F… Didn’t smell or taste chemicals on camera = Not NileRed. Could this be a real scientist?

A fellow Dutchie?

Mmmmmm.... _rare earth jelly_

1:24 I could see the grain on the video for this part

Just don't do it at home, otherwise you can not only get radioactive contamination at home, but also get a term in prison.)))

Now make thorium metal from the dioxide.

If he somehow extract Americium from Smoke detector then I would be freaking out so bad yet expected.

damn

Nice. Now smack it with thermal neutrons and make some U233

If I made thorium nitrate and mixed it with ethanol would thorium fulminate precipitate out? Radioactive primaries anyone? 🤔
