Abstract
The formation of the pore structure of zirconium dioxide at the gel aging s tage in an intermicellar medium is studied. The processes, which occur in t he course of aging, and the features of the structure formed depend on the pH of gel precipitation. The calcination of ZrO2 at 500 degrees C is accomp anied by the diffusion process of bulk sintering, which results in a substa ntial reconstruction of the pore space of the xerogel.
