48Ca has other uses. In geochemistry 48Ca (usually along with 42Ca) it is used in Ca isotope "double spikes" for obtaining high precision measurements of calcium isotope ratios. In medical research it is used as a tracer for studying calcium metabolism. Another interesting feature of 48Ca is that it actually is very slightly radioactive, transforming to 48Ti by double beta decay with a half life of something like 6x10^19 years.
It wouldn't be pure but you could make some more of it, Im no expert but it seems viable seeing as all of the isotoopes in between are relatively stable and calcium 49 would decay into argon.
Short answer:yes.Long answer:though you can theoretically make it,it would take ridiculous amount of time and effort to make even 1 mg of it(you would have to clean this up from radioactive isotopes and still separate Calcium-48). Conclusion:possible,but not worth it.
Probably but it would be stupid to do it like that if you want calcium 48. Because in the process you also make other isotope, so in the end you still need to seperate them.
I would love to see some videos covering the chemistry of the advancements in the area of solid state batteries. :) The converse of putting energy into a system where the eventual outcome is to lose the energy in a wasteful "bang", but rather designing a "battery system" where you get the energy back most efficiently. In other words, help save the planet in spite of the oil-gas and military industrial complexes. ;)
@PeriodicVideos Prof Poliakoff Looks very well thoses times :) we need more peoples like you on earth i have learn more in chemistry in 2 months of periodicvideos than all high school time i passed
I'm a bit curious. I have learnt that reactivity of metals go in the order K>Na>Ca>Mg>Al..., so why would aluminium powder have a higher affinity for the oxygen?
£500 an hour just for the calcium, still cheaper than I expected when you brought on the 2g of calcium carbonate. The machine they use to make bigger atoms must be very efficient
The same thing that would happen if you ate the same amount of egg shells or antacids.... not much. The calcium carbonate would react with the hydrochloric acid in your stomach and neutralize some of it (creating some water and CO2 in the process) , thus reducing the stomach's acidity. then it'd go into the intestines and some of it would be absorbed and used like regular calcium. You'd end up with a strange proportion of calcium isotopes in your body, but that would have no health effects at all.
Poor dude, he shakes so much he can't touch the bottle. I feel bad for him because he's probably really passionate about his craft and being in a situation where he is so close to something so rare but can't touch it must be heart wrenching. :(
Interesting, I always though that calcium metal production through thermite could not be acheived with oxides (judging by the Ellingham Diagram), that is why calcium sulfate/aluminium thermite is usually used instead.
You'd have to meltdown whatever the cyclotron is made of since the ions are travelling so fast they are probably stuck too far in the surface to just be washed off. It's more trouble than it's worth, and the target zone is worth far, far more than getting the calcium back.
I doubt it, it is call large HADRON collider not large atoms collider :D for example a proton or a neutron is a hadron. So I don't think the LHC can be used to synthesize heavy atom considering heavy have at least a few hundred hadron.
They could, but it is more designed to collide individual particles rather than particles with a target. Also the detector is designed to look at the resulting shower of exotic particles that escape after two particles hit each other with 12TeV of kinetic energy. I'm sure it could handle the calcium, but larger particles like californium might be a bit tricky to use...
@Eivilcow: No they can't aside from the size which is hundred times bigger than a hadron, you also need a charged particle so that the magnet can bend the trajectory of the particle. So an atom is out of the question, an ion maybe... edit: actually an ion is ok, the ALICE experiment is an ion collider, although atom is still out of question.
Hey Brady, I love your work here and on numberphile I think you always ask good questions. Professor Poliakoff, you have an outstanding mind and I love learning from these videos. This may be silly, but if a substance like water is put into a vacuum chamber then the water will freeze, right? But when I think of atoms and molecules in a vaccum I would picture them expanding away from each other into the open space around them forming a gas. I guess I don't understand because I have difficulty imagining it happen any other way.
$500,000 calcium? Good thing it's on sale at the pharmacy for buy one get one free this week. But you need to have the store's discount card to get the sale price.
Yesterday at the subway station, a creepy guy in a black coat approached me and asked me if I need Ca48. I told him I am not interested. Then he insisted and offered 5g for $50. I refused him again... Damn, now I see this video.
The yellow machine shown here at the SU-20 facility of Elektrokhimpribor is a calutron, an enormous mass spectrometer whose sole purpose is the separation of atomic isotopes which cannot be separated using gaseous diffusion or gas centrifugation. It was originally used for the enrichment of uranium.
Can you imagine, you just want a half million Pounds worth of calcium 48, and they misunderstand and bring you a half million pounds of the stuff that costs $250/mg? The joy of being English!
That would only work if they had all loose atoms. But the crystals contain both 48 an 40. The centrifuge can't rip apart the crystals. It's like centrifuging ice to try and get a little piece of sand out of it.
The professor gave the reason. Calcium doesn't have a gaseous compound, so it can't be separated in a centrifuge. Uranium does have a compound that is a gas, so it can. However, in some ways the separation uses the same principles, but using a magnet. The calcium is effectively gasified by turning it into ions in a vacuum chamber.
A small pile of calcium powder appeared in our living room about a week back, I tested it and found it to be heavily saturated with helium gas, I estimated it to have been initially introduced to at least a factor of 10QPS, putting the midpoint somewhere in Russia. So I had a "yep I knew it" moment when I saw this video. I doubt they are taking precautions.
Haha at :18 you gotta love the Russians... We've run out of room for the super heavy element making machine comrade! Comrade pulls an RPG out of the closet and blows a hole in the concrete wall... Get back to work comrade! Continue into the next room!
The way he talks about Calcium 48, it's importance, how to make it etc reminds me of a speedrunner talking about how they're going to beat a video game using an exploit, how it works and why
You should've seen Windscale/Sellafield. It was practically built out of temporary fixes. It's not just the Russians that played fast and loose with peoples lives regarding nuclear technology.
Calcium-48 carbonate was made for a while at the Beta calutron at the Y-12 complex near Oak Ridge, Tennessee, but that calutron hasn't been operated since 1998.
Being so expensive, can calcium-48 be somehow caught and reused in the cyclotron? Because most of it will just slip through californium without producing any heavier element!
*"You can still sniff the calcium."* Well, calcium carbonate is essentially rock dust, so I doubt you'd enjoy snorting it...like chopping out a line of The World's Most Expensive Concrete...
I feel like you guys got the idea for the video when i asked why specifically calcium 48 when you guys made the other brand new elements. Or i may be wrong.
I have a rather naïve question, but what is the point of making new expensive heavy elements? Aren't they all unstable? _ Edit: Thank you people who answered my question, I think I got it now. :)
Basic science SEEMS pointless but it is anything but. In order to do things that have never been done before you have to invent new techniques, math and technologies, any of which might have practical applications in the real world. For example, the principles behind MRI scanners were discovered by an astrophysicist. MRIs save lives and they might not exist if it weren't for a man who liked to look at the sky.
I remember when I had chemistry lessons it always puzzled me why so many reagents were potassium salts and not sodium salts. Now I wonder if the reason is the higher atomic mass. This way the more expensive anions can be sold at a higher price per mole for the same price per gram of the salt...
I doubt that would be worth the trouble -- the companies that sell the stuff just probably do some combination of whatever is easiest and what the customers traditionally use. A related factor is that solubility with different cations can be different (for instance, compare the various alkali metal perchlorates -- lithium perchlorate is highly soluble in water even at 0 `C and becomes ridiculously soluble as you approach 100 `C; this remains the case with sodium perchlorate, but then potassium perchlorate is only sparingly soluble from 0 `C to room temperature, and then becomes decently soluble as you approach 100 `C; rubidium and cesium perchlorate take another dive in solubility. The same thing happens with the detergent series alkali metal dodecylsulfate -- if you want it not to precipitate in the cold, you get the lithium salt; if you want it cheap, you get the sodium salt; if you actually want it to come out of solution (like when you want to get rid of it after it has done its work), you add a potassium salt (commonly potassium acetate) because the potassium salt precipitates even at room temperature (along with all the protein and other stuff you were using the sodium dodecyl sulfate to dissolve so that you could get rid of it, thereby leaving nucleic acid in solution)..
I haven't had a chance to read the whole thing, but looks like somebody is doing something about the lack of volatile calcium compounds: TH-cam will eat this message if I try to post the link, but search for "Synthesis and characterization of calcium N,N-dimethylaminodiboranates as possible chemical vapor deposition precursors" and the article will come up. Maybe do gaseous diffusion separation using something like this?
is it feasible that instead of moving to a larger projectile atom they just instead fire two simultaneously at the same target? Or have they already ruled that out?

I wonder how much heavier would you be if you swapped all your existing calcium for this calcium 48?
That math shouldn't be too hard to do. If you actually cared. Definitely not worth doing though.
hamilton harper you'd gain 3 grams for every kilogram of body weight. For example, a person weighing 70 kg would gain 210g.
I calculated that 17 grams. But I'm half asleep and didn't bother to actually write anything down on paper, so I might be totally wrong there.

Great video! Very entertaining and educating!
why are the numbers 20 for protons and 28 for neutrons "magic"? what makes them more stable than other numbers?? :/
tell the professor to be more specific!!! xD
A magic number of neutrons or protons will result in a higher binding energy per nucleaon, think of it as the octet rule.
en.wikipedia.org/wiki/Stable_nuclide#.22Magic_numbers.22_and_odd_and_even_proton_and_neutron_count mentions it a bit as well
thx for the link.. that makes things a little bit clearer
Very well explained, thank you very much.
If they are just shooting the atoms and most of them don't hit the target. Can't they just recycle ?
They get lots of hits,but not much hits that count.Those that don't hit get deflected and start moving randomly hitting the walls of cyclotron.
You're right. Thanks for the answer.
It would be pretty much impossible to recover the stray calcium due to the vast space it could wind up in the cyclotron
Not impossible, just very difficult.
You'd have to meltdown whatever the cyclotron is made of since the ions are travelling so fast they are probably stuck too far in the surface to just be washed off. It's more trouble than it's worth, and the target zone is worth far, far more than getting the calcium back.

I can imagine that Ca-48CO3 is heavier then Ca-40CO3. Why can't they just use a (ultra)centrifuge to separate the Ca-48 from the Ca-40?
That would only work if they had all loose atoms. But the crystals contain both 48 an 40. The centrifuge can't rip apart the crystals. It's like centrifuging ice to try and get a little piece of sand out of it.

However, in some ways the separation uses the same principles, but using a magnet. The calcium is effectively gasified by turning it into ions in a vacuum chamber.

Edit: Thank you people who answered my question, I think I got it now. :)
Kauê Researchers hope they will find an "island of stability" where there are super heavy elements that are stable enough to use.
i'm no expert but I suspect it is commonly referred to as 'science'
The main reason currently is that studying the specific ways in which they decay gives great insight into the physics that govern nuclei stability.
Basic science SEEMS pointless but it is anything but. In order to do things that have never been done before you have to invent new techniques, math and technologies, any of which might have practical applications in the real world.
