Most people here complaining about his accent. Well it's not an english tutorial so shut it. There are amazing chemical details explained here, this guy worked hard to study them and conduct experiments. You can atleast try to just listen and understand
I think his accent is interesting and I've never heard a Russian accent like that. He looks Finnish to me, and I wonder what part of Russia he is from.
You didn't mention the most unique thing about tantalum: one of its isotopes, Ta-180m! While nuclear isomers are typically very short-lived, this one is not only more stable than the ground state, it is so stable its decay has never been observed. It makes up a much smaller fraction of natural tantalum than is typical for a long-lived isotope, and is the rarest known isotope in the universe whose rarity is not due to instability. Tantalum is also the rarest element in the universe whose rarity is not due to instability
Apparently, Am-242m is the same way, though of course it's not just straight-up stable unlike Ta-180m. There's at least been talk of its use as nuclear fuel, possibly as a fuel even better than Pu-239. That said though, I've been told that there's only four stable isotopes with both an odd number of protons and neutrons: H-2, Li-6, B-10, and N-14. Wouldn't Ta-180m be a fifth one?
No, I don't mean the atomic masses are odd, I mean both the number of protons _and_ the number of neutrons are odd. H-2 has 1 (odd) proton, and 1 (odd) neutron. Just the same way, Ta-180m has 73 (odd) protons, and 107 (odd) neutrons, and is stable. Almost all stable isotopes except the five I mentioned have either an even number of protons, an even number of neutrons, or both.
Great Video! As usual. Tantalum capacitors are the highest failure rate of all capacitors. Usually because the designer does not understand how sensitive they are to design conditions. You want to operate tantalum caps at nearly their full voltage rating, but not over that. Problem is, AC noise on the DC will exceed the destruction threshold. Some noise can be of a frequency far higher than you can see on your o'scope, yet it is still present. I call this noise "hair" as it can be hundreds if not over a thousand megahertz. Your 500MHz scope shows zero, yet the caps keep burning up. We (at Prime Image in the 1990s) finally bought a 10GHz scope that discovered this issue. Not only that, they burn fiercely and usually burn a hole through the PCB permanently destroying the product. Don't use them if there is any reasonable substitute available. Only as your last choice.
videolabguy pretty much, I've had so many tantalum caps to replace on things, very true, they fry. The only exception is wet foil tantalum caps, very super reliable. modern aluminum electrytics have caught up though.
Personally I think there is a lot of batch and manufacturing technique variation; some of them seem to stay good indefinitely and some start failing in droves. But for most use cases it does not cause much damage if they happen to blow up, and the failure mechanism is pretty obvious so repairs are easy to target. Unless a lot of them are failing on one board, I think it's reasonable to replace just the failing ones with whatever type makes the most sense to you, unless it seems like further incidents could cause excessive board damage. Personally I haven't seen much smouldering-through-layers kind of action, more like popcorn going off.
Also due to ductility and density it is used for the foil cone in shaped charges, so it has military applications (antitank rounds and missiles). Surprised that wasn't brought up regarding it's conflicty-ness.
I think that this is the most informative and original channel on TH-cam about chemicals so sir Please make a video on Flouro antimonic acid(most powerful acid)as there isn't much information about it on the Internet.
Keep it up. Great work. You are giving me great ideas of science experiments with my kids. Maybe consider doing a joint video with another TH-cam star like physics girl?
I had NO idea of the Voltage vs colour electrolytic property of Tantalum. 😮 My only experience with Tantalum (IIRC, a 94%Ta alloy) was back ~1986, I was asked to make a prototype set (3 off) "heater pads". The material was ~75x75mm x 0.50mm, They were "randomly" hand cut, three sheets in an envelope with "rice paper" separators. It was smooth cold rolled with a very dark grey (likely oxide) finish. I bent a corner with my thumb and it was very soft/compliant, close to lead. The pattern... picture a PCB trace with a left & right bus bar / lug and two intricate sine-wave traces, one above the other, in phase, between the buses. Each of the 3 patterns had a slightly different "frequency" and trace width. (build&test 3/select 1). Photo / acid etching was not an option, so I sandwiched each sheet between two 6mm "ground flat" plates of aged iron (Mianite), jig-drilled the lug holes in for orientation/location, and then Wire EDM'd the patterns... in 1986, took +18hrs. Unfortunately, the product only used ~20% of the sheets so they wanted the scrap material returned by the m/gram. I didn't get to keep a sample. Also, my blueprints had the entire title blocks and notes physically removed... so I knew who it was for. 🙄
Great video again Thoisoi. Not sure if you have done Boron yet, but I would be interested to see it. An element very useful as a reactor poison (boric acid), and also in borosilicate glass etc. Keep up the good work :)
in reality he's (it is) an AI self-made by google, built to understand chemistry. This explain his accent and the robotic sound. Skynet incoming, brace yourself.
One use of tantalum i have used was for thermal evaporation of things for CVD machines. Tungsten can be used also but if you are vaporizing oxides tantalum is the way to go.
To make a protein you need ~a carboxylic acid group (RCOOH) ~an amine (RNH2) ~an arin (RCS) ~a sugar (RCHOCH3) ~and an ether/alcohol Dimethylbitriphospharin5,7dimethylpropyloic6,8glutapropyldicarboxydimethyl5,1glucose
Cleaver use of the oxide layer. Most metal oxide layers are not porous enough to refract light through so I would never have guess you could do that with it Also, thank you for these videos, I have a bachelors of biochemistry but we never really work with the higher elements outside of biological systems so it is always good to have helpful overviews into what we end up missing.
This was really interesting, now I want a Tantalum ring so I can change the color and give it to my girlfriend. Would be a unique gift for christmas or her birthday. Thumbs up for the video and thanks for the inspiration!
Also, Ta has a high work function, so doesn't sputter easily - makes a good self-heating cathode. The only refractory metal that has high ductility (tell me more!)

People are complaining? Thick accents make everything more interesting!
fnorgen 😁 yea.. Like the mad soviet scientists in hollywood films. Imagine them without their accent, would have felt so blank..
I only notice his accent for a few seconds, then I forget. He'e quite clear.
His accent adds to the awesomeness of all these videos.

Thanks for never really treating your viewers like idiots, always appreciate any extra details on chemistry. Keep it up man!

Please make a video on silicon and a very detailed video regarding it's properties and applications.
Ditto
Yes I want too

Your channel is excellent, man. Keep up the good work.
I love how he says "Tantalum" with his accent! Tan-ta-lum, I come back to watch this video just to hear him say it, Tan-ta-lum!
I love his accent! It’s him, and very easy to understand. Keep it up!
Your ideas are very funny. I love your humour.
I love your tantalum art!
What a tantalizing video.
And not only do you learn about chemicals, but also how to improve your listening skills.
Very informative, my Russian friend.
I do love your videos.
Man can I say I look forward to every video you upload always informative and entertaining👍 cheers from Australia

Great job! all your videos are super dope!!! also thank you for putting in link to buy the metals! ill be getting some soon!
Thank you! I love your channel!
Thank you. You gave me an idea about making art from Tantalum anodization.
Thank you, very cool video.
Thank You for making this video. You are awesome 😁
“Other countries have inferior potassium”, “does this car come with ____ magnet?”
Informative treatise. I would also have mentioned its use in repair of glass lined reactors.
Great work. Keep on with good job.
Oh weird. All this time I had thought the coloring on anodized surfaces involved some type of dye. As usual, the truth is much more interesting.
Absolutely amazing!!!
Love the vid. Good work !
What beautiful colors through electrolysis!
When you heated the Tantalum rod I could see it expand slightly
the great work of mr. thoisoi
Would you say this metal is.....
Tantalizing??
Burnt Gerbil helium helium helium
probably has the same greek root word for real lol

The liners of shaped charge warheads in anti-tank weapons with high penetrating power are made of tantalum in addition to copper.
The wedding ring idea is so cute :3
Very cool video .!
The art was awesome.!
The idea of adding a new band of colour to a wedding ring on ever anniversary is awesome.
next do molybdenum please
Thanks tantalum! For the cell phones!
changing the color of your wedding rings every year you're together
what a romantic chemist
He was correct, when he said that the rod turns red when abused. It should be handled by someone with soft and gentle hands.
youll start an anti metal abuse call in line. who do refer an abused rod to.

So, Where did Kazakhstan obtained Ta?

Love this show
Why do people complain about his accent? I can understand him perfectly fine. And I'm not Russian.
Tantalum is widely used as an alloying element fo Ti-Ta "biomedical alloy" - prosthesis is the best example.
Great work
great... I suggest to add subtitle and mentioned the ore minerals of any Elements (source).
Interesting details about the real life consequences of resource exploitation.
We’re are you from? I love your accent. Keep up the hard work!
Can the anodizing effect be arranged through a wide range of salts, or does it have to be done in a solution of halogen salts?
Awesome video♥️
Can u plzz make another video on lithium. I Wanna see why lithium batteries blast.
I subscribed because of his accent
Weirdly soothing?
In Soviet Russia Tantalum react you!!
Keep YOUR good video Tovarish.
Thanks for this information
Wow, this is really interesting an useful.
Thank you!
Good video, im gonna do some experiments with mine.
thanks for that informative video sir (Y)
Thanks a lot for sharing information..
Hey really loved your videos. By the way will like to perform giveaway that tantalum sheet with your channel name. It's kinda really cool

Sir is it possible for you to cover physical, Biological , Chemical and electrical properties of the elements or substance. Thanks
Cool Video !
Sometimes the ads are interesting and sometimes the ad music is as good or better than top 40
Now I really want a Tantalum ring
You can make some nice knife handles out that. Hit it with a couple extra amps to what ever color you want
"dont forget SAFETY IS NUMBER 1 PRIORITY'
Great stuff
Tantalum is my favorite element. I love its natural gunmetal color.
I also collect the Silver/Tantalum bi-metal coins from Kazakhstan.
You are amazing!
a 24v electrolyted ring would look amazing
Mmmmmm yes time to get into the tantalum business
Excellent!
thank you
This one was really good. I would like to see more about different elements effect on the world.
great job
