Surface tension can generate capillary pressures high enough to crush fragile gel structures, turning them into dense xerogels instead of high performance aerogels.
Our new blog explains how supercritical fluid drying sidesteps the liquid–vapor transition entirely, using supercritical CO₂ with zero surface tension to protect pore architecture and deliver consistent material properties.
The link in the comments is a must read if you work with aerogels, advanced insulation, or precision porous materials!
