Aerogel?A Transparent, Porous Superinsulator

by Arlon J. Hunt, Lawrence Berkeley Lab, Berkeley, United States,



Document Type: Proceeding Paper

Part of: Materials: Performance and Prevention of Deficiencies and Failures

Abstract:

Silica aerogel is an unusual, transparent, low density, thermally insulating solid useful for a variety of applications. We have been investigating silica aerogel for use in transparent and non-transparent applications. When used as a transparent vacuum insulator between double glazings it has a thermal resistance of R-20 per inch of thickness and greater than R-30 per inch for non-transparent applications. We report recent progress in the preparation of transparent and non-transparent silica aerogel and the status of scale up and commercialization activities.
