Formation of the pore structure of zirconium dioxide at the stage of gel aging

  • V. Yu. Gavrilov

The formation of the pore structure of zirconium dioxide at the gel aging stage in an intermicellar medium is studied. The processes, which occur in the course of aging, and the features of the structure formed depend on the pH of gel precipitation. The calcination of ZrO2 at 500°C is accompanied by the diffusion process of bulk sintering, which results in a substantial reconstruction of the pore space of the xerogel.
