Aerogels- The Lightweight Wonders of Modern Materials Science

Aerogels are fascinating materials, often referred to as "frozen smoke" because of their light, airy, and translucent appearance. Essentially, an aerogel is a substance that's primarily made up of air, with a very small amount of solid material—typically silica, but also other materials like carbon or polymer-based substances. The process to create an aerogel begins by turning a gel (a substance with a solid network holding a liquid) into a solid, but crucially, it replaces the liquid with air in a process known as supercritical drying. This process allows the material to retain its porous structure, which is why aerogels are so light—up to 99.8% of an aerogel's volume can be air.
