How to Make Silica Aerogel: Part 2 (#8)

The second in our two-part series focused on the actual process, that is, the art, of making silica aerogels. This episode covers how to prepare gels for supercritical drying, how to perform solvent exchanges with organic solvents and liquid carbon dioxide, and, last but not least, supercritical drying. The conversation is geared towards using a supercritical dryer like the one presented under the Make section here on, however applies to any suitable supercritical dryer. If you’re already making aerogels and having trouble with cloudiness or cracking, we think you’ll find this episode particularly helpful.
