Making Aerogel
Added 2020-03-27 05:39:40 +0000 UTCHey guys, I haven't posted for a while because it has taken me forever to put this together. I was finally able to make some aerogel! It's also the longest video that I've ever made.
Let me know what you think. Patreon credits will be added in the final version.
Oh, and this was a charged post, but with the whole COVID stuff, don't AT ALL feel bad if you can't pay for this video. I totally understand that money is tight right now and you should do what is best for you. On my side, things aren't ideal but they're okay and I'll more than survive without Patreon support, especially because this video is going to be sponsored.
But with all that being said, stay safe out there guys!

Incredible work! ππΌ

2020-03-31 04:24:26 +0000 UTCwith waterglass the precise control of the internal structure is lost, so I guess the result would be quite crappy, more like airy silica gel. But the article is interesting though!

2020-03-27 18:08:49 +0000 UTCIt is kind of like silica gel. It was like glass rice crispies.

2020-03-27 18:07:39 +0000 UTCIt's possible, though much more arduous than supercritical drying. Check out this paper, which reports densities down to about 0.1g/cc: https://doi.org/10.1016/j.jnoncrysol.2018.09.049 (sorry about the paywall) Edit: also, they used MTMS for that paper, not TMOS. I still think it should be possible, but it might be harder with water glass.

2020-03-27 18:03:55 +0000 UTCTMOS hydrolyzes more rapidly than TEOS, so the sol prep step can be carried out with fewer ingredients. The hydrolysis of TEOS typically requires a catalyst to make it work properly (aerogel.org recommends ammonium fluoride).

2020-03-27 17:59:41 +0000 UTCI have tried and succeeded at gelling up water glass, but I do not have a supercritical chamber. Is it possible to make aerogel from gelled water glass? Or the density would be much less than what we consider aerogel, and more like silica gel?

2020-03-27 13:38:13 +0000 UTCvery good video, with lots of interesting details! One of the best I have seen on aerogel, it was well worth the work you have put into it. When you have air dried the gel, you got silica gel, right? It looked and fizzled like very airy silica gel.

2020-03-27 11:32:29 +0000 UTCI wouldn't dream of withdrawing my support. Especially now.

2020-03-27 10:04:23 +0000 UTCAmazing and congratulations! Your projects have constantly been an inspiration to me and seeing the amount of work and research that was put into this really puts into perspective how impressive the final result came out to be.
2020-03-27 08:18:50 +0000 UTCwhat are the advantages of using TMOS over using TEOS?

2020-03-27 07:31:22 +0000 UTCWow! Congratulations! Nice job!
