| Popis: | The mesostructure of amorphous xerogels based on hydrated zirconia ZrO2 and its evolution at different stages of heat treatment have been investigated using the small-angle neutron scattering method. A correlation function of the nuclear scattering amplitude density has been obtained from experimental neutron scattering cross sections, and the characteristic radii of ZrO2 nanoparticles and their specific surface areas have been determined. The influence of the annealing temperature on the fractal properties of the zirconia surface has been elucidated. |
