Transparent silica aerogels for window insulation

open access: yesSolar Energy Materials, 1983
Abstract Supercritically drying a colloidal gel of silica produces a porous material called an aerogel. These aerogels not only are excellent thermal insulators, but also can be highly transparent. We investigate the microstructure and optical properties of transparent silica aerogels and calculate the energy transfer through hypothetical aerogel ...
