a Link to a recent Aerogel articleAnyone mess around with this stuff at all? Is it still a bit on the steep side price-wise ?As a Building materialNotice in the picture how well it insulates against a torch flame:

Bumping an old posting to include a relevant link:http://blog.makezine.com/2012/02/01/how-to-build-a-supercritical-dryer-and-make-your-own-aerogel/
Ha, I just popped over to post this:How to make aerogel.
Interesting. The MAKE article links to "cat=10", which ends up the same as your "cat=41" URL.
There are many ways to skin a cat.
Some ways could end up "cat-a-strofic" however.
If it walks like a duke, and quakes like a duck.....
Marketech will sell you smaller pieces for about $15/gram (minimum size 10g for $135), and a nice 4x8 inch slab for about a grand. There are some other sources listed on Hubert's Aerogel page.Some of the 1+F supercapacitors claim to be based on carbon aerogels...I've always been a bit disappointed that you can't seem to make an "amost aerogel" in a home lab - after all, you can make a water-filled silica "gel" by mixing acid and waterglass; in theory all you need to do is remove the water without letting surface tension destroy the silica structure. In practice, though, it is pretty hard...There seems to be an increasing supply of aerogel in coarse granular form (probably MUCH easier to make, but not as neat.)And trebuchet03 is right; fumed silica is sorta the same stuff. But it's barely solid...

I thought it looked rather interesting. Sadly things like this are always out of my budget range -)
yeah, i remember hearing about this stuff it would be neat to own if i had the money for it
It's still pretty expensive, and not sure how good of a building material it is. The problem with aerogel is that stuff can get imbedded in it really easy, infact NASA's using it to collect data from plannets by forcing the dust easily into the aerogel so that nothing can crush it, so everythings the same, such as density.
Aerogel is also the world's lightest solid.
Feel free into asking me questions, I was really into it about a year ago, but never bought any.
