Episode 3 of my series on water ice! In this video I walk through my process for vapor-growing single crystals of ice. Starting with a small single-crystal substrate, a large crystal can be grown by depositing vapor. I use a vacuum chamber to evaporate/sublimate water at about -20 celcius, then a peltier cooler to deposit that water vapor back into a solid. The awesome thing is how crystallographic the samples look - lots beautiful hexagonal facets!

I don't think the heat sink and peltier junction are thermally bonded. They are physically bonded with pressure from the nuts and bolts on the bracket you made. The instructions for using thermal compound between a CPU and heat sink say to use a single drop in the center and pressing the two together while keeping them parallel. That way all air bubbles are avoided and you won't overheat a micro spot on your CPU. (I've done this for two, old, used computers, which never burned out a CPU. They eventually failed when the mother boards developed problems.) I cringed when I saw the wavvy blob full of ridges of air on your heat sink.

@AlphaPhoenixChannel 3 года назад

@multipleaser That was not the way it actually ran - I did it the right way, with a small blob smeared out with pressure - i even filmed it from up close with a macro lens to get the squish, but somehow that footage got lost, and I ended up with a clip of that gross blob from early in the process (note that it had two peltiers on that one too), and that clip itself was ALREADY a recreation, which is why there was an awful blob on top of already flat stuff.... sorry it was cringey - i agree!

@4LO4LO 3 года назад

Just a suggestion, if you ever need degassed water again, you could degas your water by keeping it just below the boiling point for a long time (ideally for a day or two). Then you could boil some of the water off, rig steam to your peltier chamber, then vent your peltier chamber (at net positive pressure) to atmosphere to ensure it is filled only with steam (by displacement/dilution). Degas complete without potentially harming your pump. Either way, you got the results you are looking for. Good job. This was a really educational and fascinating video, and you are a good storyteller.

The MIT underwater snowflake machine for years was on display at the Museum of Science in Boston. Two of them! (so, as one was melting and re-chilling, the other was making snowflakes.) I was the tech manager there at the time. Each was a flat cell of supercooled water, mounted vertically, w/side lighting against black background, (with glycol cooling for rapid temp changes,) plus a 1cm coldfinger near the top, to produce a large excursion and nucleate some seed crystals. As they fell, the dense seeds grew to thin snowflakes up to 30mm wide, piling up at the bottom of the water-cell.

@ssholum 3 года назад

Very cool seeing those hexagons finally! Reminds me of when I learned about the process for making monocrystaline silicon wafers. The nano-scale doping process for making devices was also cool, but there's something amazing about taking a tiny seed crystal and pulling a giant bullion out of molten material.

@AlphaPhoenixChannel 3 года назад

@IainMcClatchie 2 года назад

@@AlphaPhoenixChannel SunEdison had one in their lobby a few years ago. 20 feet long! That's 4000 wafers or so. Silicon is zone refined, which I think means they melt a cylinder of it from one end to the other while pulling heat out both ends. My understanding is that for this to work, the silicon would have to solidify as a single crystal, otherwise they'd collect impurities in the grain boundaries. So that suggests there are two ways used to make single crystals, the Czochralsky method but also this simpler freezing in the zone refining container. Or is zone refining done with the Czochralsky pull at the top? If not, why bother with the Czochralsky method? They need to align the crystal orientation to the boule axis, so that the wafer can have a single crystalline face. Maybe the zone refining process doesn't give control over the crystal axes. I wonder if there is something you can do with zone refined water that wouldn't work in presence of even tiny amounts of impurities. I can't think of one myself, which makes demonstrating zone refined ice less interesting.

@@IainMcClatchie zone melting refines the purity because the dirt will travel along with the melt zone preferentially, rather than crystallizing out. Essentially sorta like freeze-distilling.

@russellking747 2 года назад

Pro-tip: Ever noticed that large crystals are usually produced in a liquid bath? PRo-Pro-tip: why don't you just seed a crystal on demand? I accidentally did this once - funnily enough using a peltier the other way around: I had a sodium acetate heat pack, and wanted to measure the temperature point at which the seed clicker stopped producing seed crystals - I was using a peltier as a heater to accurately maintain the temperature of the heat pack, as regulating the thermal output of a peltier can be done slowly by setting the power electrically and make quick adjustments by varying the temperature of the cold side (with another peltier); I found that I was getting a large single crystal at around the 56°C mark (it took ages), rather than the dentral slush that usually forms. I could not get a crystal at all above 57°, although this could have been error in my temperature sensing (I was using a schottky diode as the sensor and crude temperature readings from several sources to map the voltage drop to a temperature gradient). The most prominent result from this is that I didn't see dendral formations if I regulated the temperature of the sodium acetate within a couple of degrees below its freezing point. I also noticed that spawning the seed crystal often resulted in a single crystal - maybe because of the very low probability at the temperatures I was doing this at. This video reminded me of that experiment. Maybe this could be better way of getting a single ice crystal? The method: Supercool pure water to a couple of degrees below zero, spawn a seed, and regulate temperature as close to below freezing as possible - note that this is somewhat self-regulating, due to the supercooled freezing effectively raising the temperature of the medium as the ice forms - you only have to keep the liquid bath temperature constant and slightly below freezing. Just a thought, hope it helps.

@charliesteiner2334 3 года назад

Vacuum pump tip: run the water vapor through a cold trap before it goes to the pump. The "cold trap" can just be a part of the tube that you dunk in a dry ice ethanol bath, but that will get clogged easy - better trap geometries can require brazing tubes into bigger tubes though.

@antivanti 2 года назад

A note on freezers. While they can achieve a decent difference in temperature between inside and outside they can only move a certain amount of heat per unit of time so if you try to cool a heat source with a bigger output of heat than that it will eventually just act as a big insulated box that gets warmer and warmer. This is why you cannot cool a gaming PC in the freezer. Kind of like how your initial insufficiently cooled stack of peltier elements ended up heating rather than cooling 😊👍

I'm glad I stumbled on this video again. I've recently been growing crystals from different chemicals. Nothing fancy, calcium acetate, sodium acetate, salt, calcium carbonate, citric acid, which makes very nice crystals. But I could never get them more than about 1cm at the largest. I'm more or less trying to do this "discovery style" just exploring and discovering it all on my own without reading anything (or very much) about it. I think even though it's about ice, the principles in this video could be applied to my own crystal growing attempts.

@useazebra 2 года назад

Great video! As i understand it, attempting to grow a single crystal is really tricky, imvolving a lot of effort to maintain the right concentration of available atom, ions, or molecules PLUS the right pressure PLUS the right temperature,and possibly sometimes the right electrical charge. As near as I can tell, the people who have figured out ways of depositing perfect crystals of interesting substances (diamond, sapphire, lithium flouride used in JWST lenses) guard their secrets pretty tightly.

My thoughts on this so far, de-gassing the water and the distillation process is giving you a beautifully pure crystal of water, brilliant use of the peltier waste heat! Second, run your vacuum line through molecular sieve, it will save your vacuum pump. An activated carbon trap will also scavenge excess N2 and O2 also if you leave it connected to the vacuum chamber.... I think! But, your experience in molecular epitaxy chambers is probably going to give you a far better grasp on this than I!!! 😂

Very nice work! The thermal loop and the filling of the chamber with water vapour is a very elegant solution. I remember suggesting trying to use a pettier to grow a crystal from liquid water in the last video, but that would require a setup more complicated than this one. Crystal growth might be different in nature though. Only suggestion I have now is to add a tiny camera (like from a raspi or USB/laptop webcam) inside the freezer to get a time lapse. But I’ve no idea if a CCD would work at those temperatures, not to mention in a vacuum chamber.

@AlphaPhoenixChannel 3 года назад

I tried just submerging the peltier in water in the vacuum chamber instead of only partially filling the chamber and never saw any facets (despite what the literature told me...) And don't worry - I have PLENTY of timelapse of growing crystal set to release. I'm really pleased with it - I put the whole big mirrorless camera in the freezer for like multiple weeks total. I think i'm going to release a very short "how to film in the freezer" follow up video as a technical interest
