Description

Silica aerogel is a nice thermal insulation material. It has excellent characteristics like nano-structure, high porosity (more than 95%), large surface area (about 1120 m2/g), low density (0.003 g/cm3) and low thermal conductivity (0.023 W·m-1·K-1). Some new processes were studied to reduce the preparation cost of silica aerogels. thermal conductivity was measured. The thermal transfer mechanics was analysed, and different kind of insulation materials were compared. (authors)
