Aerogel and method for manufacture thereof |
| abstract |
An aerogel with excellent thermal insulation performance, average particle size of 1 to 20 μm and globular shape; and a method of manufacturing it efficiently, is provided. The aerogel has specific surface area by BET method of 400 to 1000 m 2 /g; pore volume and peak pore radius by BJH method of 3 to 8 mL/g and 10 to 30 nm, respectively; average particle size and average circularity by image analysis method of 1 to 20 μm and no less than 0.8, respectively. The method includes the steps of: preparing an aqueous silica sol; dispersing the sol into a hydrophobic solvent, thereby forming a W/O emulsion; causing gelation of the sol, thereby converting the emulsion into a dispersion of a gel; replacing water in the gel with a solvent having a small surface tension; treating the gel with a hydrophobing agent; and removing the solvent used in the solvent replacement. |
