Abstract
New composites based on a matrix of silica aerogel grains are currently being developed to answer the expectations of thermal renovation. One of the key parameters for their commercial use is the control of their porous network. In this study, we aim to propose a three-dimensional characterization from the nanometer to the millimeter scale of the silica aerogel particles themselves. Transmission electron microscopy (TEM) is used to characterize the mesoporous network within the aerogel grain. The arrangement in three dimensions of the grains and the voids within the aerogel grain pileup is investigated at the micron scale by X-ray tomography.
