Tom, re-melt the lithium niobate you made but use an oxygen rich oxidizing flame instead of the reducing fuel rich flame you used, it will oxidize out all the carbon that it got impregnated with and clear up. Don't be afraid to get the whole crucible glowing hot, it just means a slower cooling time that will yield better crystals.

Here's a fun fact about niobium, it's one of the most problematic trace contaminants in steel for the future fusion reactors. Nb has a huge neutron capture cross-section and it gets activated into a nasty Nb-94 isotope with 20000 year half-life and high decay energy. As a result, normal steel activated by fast neutrons from fusion will have to be treated as a low-level nuclear waste basically forever. One of my classmates worked on a project to make low-niobium steels, but they kinda gave up on that.

Actually, you can get hot enough with your microwave, I played with this about 20 years ago (for fun) and I reached about 2400°c . I used a old analog pyrometer from the sixties so not ultra-precise but I have definitely melted alumina. I used polishing grade coarse SiC as the microwave absorber (susceptor), I think it is the black thing rather than graphite that is placed inside your kiln but there is not enough to absorb all microwaves (it is on purpose i guess). My advice in the same kiln put a thick bed of alumina power put some SiC powder on top ,cover it with alumina powder and then put your alumina crucible on top (of course try to have a good contact area with crucible and the powder below but without direct contact crucible-SiC). If you put the alumina crucible directly on top of the SiC, it will shatter due to the thermal shock.

Tip for the acetylene torch. Your inner flame cone is too large. Less acetylene or more oxygen to get a neutral to oxidizing flame. Right now it's more carburizing. You're putting carbon into your product. Also for lighting it: half a turn oxygen then quarter turn acetylene to start with, adjust it from there. If your pressure is to high or low the flame will go out. To turn it off, first the acetylene then the oxygen. If you do it the other way around you get a lot of soot that is actually a little carcinogenic. And for the love of fuck don't light it with a liquid or gas fuel lighter. Use a striker. There's a tiny explosion every time you light your torch. If this damages your lighter it can catch fire in your hand. Which can be kinda bad since the torch is blowing oxygen at it. If you smother you torch by accident and the flame goes into it. Just turn it off like normal. The torch will start getting hot pretty quickly as the brass sucks the heat out of the flame and it travels up the torch. If it goes past that into the hose, shut off the valves to the bottles. to prevent them from further turning into little rockets. be safe and happy lighting shit on fire!

That was a nice video! I've actually worked with amorphous niobium oxide (sometimes called "niobic acid"), which I believe is the exact material you made here (didn't make it myself, we ordered it from a supplier). It has a very high surface area, and can hold on to a non negligible amount of water, even as dissociatively chemisorbed species (i.e; surface hydroxyls). We used it as a support for catalysts. So that extra water might explain why you got 100% yield despite the mechanical losses. And cool to see you got an acetylene torch! You may want to try making an oxidizing flame, so that you don't leave carbon on your metal oxides... (I think "cutting tips" are designed specifically for that. I've only used those torches to seal glass ampules though, so don't take my word on it.)

I'm a big fan of lithium niobate crystals. If you put a c-axis cut under weak vacuum (like 10^-4 torr) and cycle the temperature the uncompensated charges exposed on the ends act like a particle accellerator and you can achieve electron and ion beams up to ~200KeV. That's without any moving parts or high voltage. If the crystal is radially symmetric the beam self focuses. If the residual gas in the weak vaccuum is deuterium and you have a deuterated plastic target you can even make a linear accellerator fusion device for making small neutron fluxes. Definitely a fan.

For a cleaner product after melting with the torch you will need to have complete combustion of the acetylene. This is a achieved by using more oxygen as I’m sure you know. If you watch a KZread video about acetylene welding I think it would help you get the flame profile you are looking for

Niobium isn't obscure! It's a part of one of my favourite minerals - columbite-tantalite (or coltan), which is (Fe, Mn)Ta2O6-(Fe, Mn)Nb2O6. This mineral is primarily mined for the tantalum therein, as it is used in capacitors in modern electronic devices, but niobium has a lot of extremely high-tech, science-y applications too, mainly in the steel industry (where it is alloyed with stainless steel to give it strength at low temperatures, which is handy for a lot of aerospace applications*), superconducting magnets (600 tonnes of Nb3Sn alloy is in the Large Hadron Collider, while the International Thermonuclear Experimental Reactor uses 600 tonnes of Nb3Sn alloy, and another 250 tonnes of NbTi alloy), and high-performance lithium batteries. It can even be used to make people's glasses thinner, as it increases the refractive index of glass. *The Gemini and Apollo space programs both relied on niobium to make their rocket engines, and SpaceX is currently using such an alloy for the engine of the upper stage of the Falcon 9.

If you had a neutral flame on the torch it would've melted better, it looks like you were running acetylene rich by how orange the flame was. For a neutral flame you want to balance them so that there is a single bright cone in the middle of the flame, and most of the flame should be blue with just the end of the flame starting to turn to orange

As a gem cutter and jeweler, niobium is awesome and lithium niobate is amazing as a cut gem!

Niobium alloys are common in rocket engines because of the high temperature material properties. They're a bit of a pain but sometimes you just need it.

It's also biologically inert and used for jewelry, piercings, surgical hardware etc. But that's not why I have it. It's also a grain refiner and very strong carbide forming element in steel.

i actually cracked a liebig once using a forced air condenser when distilling sulfuric acid (similarly to how you did a few years ago, right on the jacket), id recommend using a vigreux column instead and keeping the sulfuric at such a rate so that the convection cooled vigreux can keep up with it. that glass stir bar had me worried a little since glass can scratch glass and with hot sulfuric acid you dont really want score marks on the glassware for obvious reasons, though i still probably will buy some as theyll be perfect for something i have planned. as for that SO2 like you mentioned its probably the reaction, ive dissolved copper in hot sulfuric acid and the sulfuric acid gets reduced to sulfur dioxide while the copper oxidized to copper oxide which then forms copper sulfate so that blue tint may have been niobium sulfate or sulfite but unfortunately i cant find pictures of those so idk. cracking the flask like that ive done too many times, its not a good idea to heat a wet flask with a flame or run liquid onto hot glass like that, as for melting maybe an arc furnace though that may spit graphite in from the electrodes, neat video like always

So I just got done watching a NileRed video, and the way each of you go about things is so vastly different, its both jarring and amusing

Well Tom, I took the entire transcript of this video and copy-pasted it into GPT3.5, and this is what it had to say: "Thank you for sharing this detailed episode on the extraction and use of niobium. It seems like you had an adventurous journey in working with niobium metal and converting it into niobium pentoxide. The process of dissolving niobium metal in sulfuric acid, followed by the formation of niobium pentoxide and its subsequent reactions with lithium carbonate, demonstrated your exploration of different chemical reactions. The use of a microwave furnace to achieve the required temperatures for the reactions, as well as your attempt to fuse the niobium pentoxide using an oxy-acetylene torch, showcased your resourcefulness and experimental approach. While the results may not have been as expected, it's clear that you enjoyed the process and learned along the way. If you have any specific questions or need further information about niobium or any other topic, feel free to ask!"

So happy to get more extractions and ire/fire vids while you are procrastinating your thesis. 😂 For real though best of luck/skill on your doctorate sir!

E&I is like a box of Whizzo Quality Assortment, you never know what you're going to get next. It could be Crunchy Frog, or it could be the Steel spring surprise.

Glad someone was there to guide ya on that kit. Acetylene is some dangerous shit if you don't know what you're doing. Glad to see another vid!

always happy to see a vid

i took an art class at my local college and they had these microwave crucibles, they put ceramic shards on the plate to allow the crucible to continue to rotate without damaging the plate. also i noticed in that class that different microwaves heat faster so if you hate the 30 minute wait you should consider testing your friends microwaves and buy the hottest one you tested.

Awesome to see some new Extractions&Ire! super cool use of a microwave as a rudimentary kiln, i wonder hot hot you could go with some additional modifications, perhaps focusing the magnetron's waveguide to the centre of your crucible in some way~

I used to be a niobium man myself. Built RF cavities for linear particle accelerators out of it. Definitely in my top 3 superconductors.

In college I was an intern on the Stanford Free Electron Laser facility (now torn down) which used a niobium superconducting array as its electron accelerator.

Brilliant as always good sir!

Huh, what a happy coincidence, I just recently got some faceted iron-doped Lithium Niobate. Apparently used in research as a holographic storage medium. Sure is a pretty shiny rock, too. Would definitely like to hear more about your PhD thesis when you're able to.

Awesome work man!

I love your videos cuz unlike others we never know whether it will work, or if it will become a mess

It reminds me of the old alchemists- found a new kind of metal, let's boil it in acid, dilute, precipitate, basify, and see what it does

Always expecting chaos in my day, when there's non this guy's here for me. True legend

I really love the mad scientist working in a shed with trash equipment (no offense) vibe we get here. This channel deserves more views. It would probably help to "spice" up the production value (but keep the vibe!).

new to this channel, first vid and already loving the content. i hope the crusty fan makes more appearances

Everything you do is the best!

Even knowing i mostly don´t have clue about what you are talking about, damn you make it intresting. Also love the Board and all the scribbls on it. Keep up your Love.

A guy made Cubane and called you out but we all know you are still the best chemist on youtube.

Haha aw thanks, his video was great tho! I’ll do another cubane video soon

Gonna watch the next one because that was fun to watch

award for best music in a extractions and ire vid goes to this one btw

I love that Tom is doing crazy technical chemistry, and says 'I think' and 'I don't know l, we'll see' so much more than the average person does doing mundane things they've never done before. (Most people don't ever attempt anything they don't know how to do, lol)

I won’t lie, I was on explosions and fire and thought you just stopped uploading, but seeing this was a bastion of hope

Don't get tired of saying. I know sh** about chemistry, and this is one of my favorite channels. So much fun
