The evolution of the texture of silica aerogels during sintering is studied by thermoporometry for both neutral and base catalysed materials. During the densification the macroporous volume drops and the analysis of the mesopore size distribution evolution shows that the collapse of the smallest mesopores is responsible for the macropore volume transformation. However, corrections of the measured volumes are necessary to characterize the most compliant materials.
