It seems like you've got the tungsten rod sealing under control, but there's also the option of an induction pump using alternating magnetic fields, including the circle arc duct electromagnetic pump--a spinning magnet array next to a circular arc tube pushes along the fluid inside. Might be a good option later or not. See Sodium-NaK Engineering Handbook Volume 4 Section 1-3, either for an overview or just because all those books are a cool overview of the state of the art of 1970s NaK engineering.

In theory it will work with any electrically conductive fluid, but mercury is not an ideal choice. It's very dense so it needs a lot of force to give it enough of an upward push to make a fountain. It's also a pretty bad electrical conductor for a metal (I think about 1/3 or 1/4 as much as NaK) so you need to apply a much higher voltage to get a good current flow. Actually, the reason mercury is a bad electrical conductor is the same (fascinating) reason that it's a liquid at room temp. It has to do with its outer electrons moving so quickly (faster than 50% the speed of light!) so they effectively gain significant mass and are more tightly bound to the nucleus, making them less available for metallic bonds. Anyway, I'd be much more interested in seeing a caesium fountain!!

Gallium would be an option. But you would have to use very pure gallium and also work under an inert gas atmosphere to prevent oxidation. Because gallium oxide will stick to the glass. Or you would have to coat the glass. The larger issue is the high density of gallium. It is appropriately five times more dense than NaK. Which also makes it harder to accelerate. It could be possible with a stronger magnetic field and higher currents.

This whole video was an absolute pleasure and you had my attention glued to the screen, bravo!

Have you considered sealing it permanently while full of NaK and building a protective permanent support for it? I think it would make an excellent workshop or breakroom showpiece; what better way to show off your efforts and skills from this point in your career than with something unique, unusual, and visually striking that is also a fully functional display piece showcasing a cool effect and material that normally aren't seen in everyday life? If you submerge the bottom half of the apparatus in clear epoxy it will serve both to protect the fragile pump section and create a sturdy base to support the weight of the whole piece. There are so very few people skilled in scientific glasswork today, and I feel that their (and your) works deserve to be appreciated for the art that they are. It doesn't have to be perfect to be beautiful, and the pieces you've made for this reactive alkali metals series are most definitely beautiful! I personally love the inclusion of some glassworking footage, especially when it is put in context to the overall project's gradual completion as was done in this video. I think you could show a bit more of it than you did here too, not just more often as in showing a few more of the key steps, but also show slightly longer clips of your glasswork, too. P.s. if you make a third tungsten-glass passthrough and attach it to the very top of the tube you can drop the tube to reduced pressure when sealing the vacuum port at the last step, then the tube will double as a gas discharge tube and a magnetohydrodynamic pump tube. Use the Nak pump connection as the Anode and the top connection as the cathode and you'll be able to vaporize some NaK while cooling the anode via pump action, making for an efficient LPS NaK lamp!

Hi, thank you for the comment, your kind words, and your feedback! I am so happy to see that people enjoy the stuff I am doing. Yes, I thought about making a permanent display piece out of the fountain. But I think I have to optimize it, before doing so. The glass tube where the NaK squirts out of is not perfectly centered and vertical. But man, it’s so hard to get it right without a lathe for flameworking. And I have to get a better oxygen and water free environment inside the fountain. You can see in the clips at the end, that there is some oxidation happening. I think mostly because of water adsorbed to the glass walls. So maybe, if my tungsten/glass seals are good enough, sealing everything under vacuum would be best. That way I also do not have to be worried about pressure building inside the fountain when it heats up. And it would make your fountain-LPS-NaK-Lamp idea possible (awesome ides by the way. I think it would look great having the liquid metal moving around inside, while the gas is glowing). But I think that’s something for a future project. By the way: I did not forget that you wanted to see the Potassium spectrum. And I did build a “low pressure potassium lamp” and filmed it. The problem is that the color does not show on the camera properly. Its just glowing bright and color looks nothing like it does in real life. That’s why I did not release the video yet. I want to find a way to color correct the video or get a better camera to film it.

Slope of tube shouldn't matter. You have trapped gas. Evacuate partially & re-fill several times with NaK in place. This will "de-air" the tubes. Why are you wasting the NAK you filled the first time? Can't you invert the tube & re-capture it in the syringe? When preparing tungsten rods for glass sealing, there is an "alchemy process" where you rub the tungsten with a nitrate? salt & heat. Why not buy a pair of neon-sign electrodes? Your magnet needs "back iron". Having this will multiply the field by 5 (& reduce the current by 5). Get a 1/2" thick piece of steel & cut it into a "tuning fork" piece (shaped like your 3D printed piece) except wider space between so the magnets can be stuck between (no need for screwing the magnets, they will stick firmly to the steel. DON'T have holes in the magnets. That further weakens the field!)

And that's where I think a steeper angle of the tube would help. -I did "recycle" all the NaK that would come out the fountain when it was inverted. But due to the oxidation, some of it sticks to the walls and it's nearly impossible to collect.

I actually thought about doing it with cesium. But there are several problems: 1. Cesium is a lot more dense than NaK, which means you would need more force to move it upwards. 2. Cesium is so much more reactive and oxidizes much faster. With the surface area created by the fountain it would oxidize very fast if the atmosphere is not perfectly dry and oxygen free. And that a lot harder than it sounds. But I think you are right, the heat dumped in the metal would probably keep the cesium in a molten state.

Why does the height of the elected NAK fluctuate? Fluctuations in the magnetic field? Fluctuations in the power supply? Connective currents acting upon it? Hey from outside the apparatus?

Would this aparatus work with mercury rather than the extremely dangerous NaK ? or even galium although that tends to stick to the glass..

You can move Gallium or Mercury with this type of pump. But mercury is so dense, I highly doubt it would work as a fountain. Even Gallium might be to dense for this purpose.

Excellent work! Can you try it with cesium?

Thank you! I have thought about using cesium. But there are two problems. 1. Cesium is a lot more dense than NaK. So I think it would be challenging to propell it up with enough force to get a decent jet. Maybe if I increase the magnetic field even more. 2. It is way more difficult to handle cesium without it oxidizing and ruining the look of the fountain. I would love to try it, but cesium is way too expensive to just try it. But I am still thinking about doing it in the future.

If we are just talking about the "crude" metal approximately 2-3$. It really depends on how pure it needs to be. If it needs to be really pure the time I have to spend(especially making the glassware) rises quickly.

What are the advantages of using NaK instead of some other liquid metal like mercury or gallium?

Hey what would be the best setup to get into glass working? Do you think and HHO burner off amazon might be good?

@AdvancedTinkering

Жыл бұрын

You don't need a HHO burner to work with borosilicate glass. Hydrogen/Oxygen is used to work with quartz glass. Propane/Oxygen works great and is a lot safer. I wouldn't recommend using a HHO generator. As far as I know the flame from those generators is pretty small. I would recommend using an Oxygen concentrator, a cylinder of propane and a proper torch. I made a video about my equipment a while ago.

Can you make a Caesium fountain?

Would gallium or mercury also work for a fountain like this?

You said "Lorenz force" lol :D

Is NaK a ferrous alloy type metal? I figure it would be non-ferrous

Silicon sealant wouldn't work?

That's pretty. Have you considered running the fountain under mineral oil instead of Argon? Would the MHD pump be powerful enough for that even?

@AdvancedTinkering

Thank you! Yes I have thought about that and it should be possible. But I think it would ruin the looks of the fountain because the oil will stick to the glass. I may try it in the future.

@@AdvancedTinkering I mean, if the oil fills the tube it should be optically clear throughout? Plus if you can get it to run under oil you could cool the oil to have the fountain run for longer. Ofc, the pump being what it is is technically interesting, but the current draw is bonkers. Another way to do a more traditional pump would be to use a classical impeller style pump, but with the impeller embedded in a glass cavity and magnetically coupled to an outside motor (or maybe even constructed like the rotor of a brushless motor). That'd be more complicated to make, but would substantially reduce the current draw. I'm just thinking out loud here, looking for ways to make it more efficient are safer to run for longer periods of time. Then again, this'll probably never be made into a decorative object for obvious reasons.

Oh you mean completely filled. I thought just a layer on top of the NaK. For that I think the pump would not be strong enough. Yes some aquarium filter pumps work with a magnetically coupled impeller. That would also be a great idea. But I don't think I am able to make something like that out of glass.

@@AdvancedTinkering Hmm. Maybe there's a hybrid way of doing this. Like some piece of glass ware that can house a magnetically coupled impeller (could be a 3D printed one or something pre manufactured that is even more heat resistant) and then splice that piece into the loop as the pump (my thinking is, the impeller made of plastic needs to be kept far enough away from the heat source for splicing the part into the loop). Then again... how reactive is NaK to ferromagnetic metals like iron or steel? Those wouldn't melt in the glass blowing process and could be magnetically coupled just as easily as another magnet in a plastic impeller.
