Abstract

The mesostructure of amorphous hydrous zirconia xerogels and the products of their heat treatment was studied for the first time using powder X-ray diffraction and small-angle neutron scattering (SANS). The samples prepared at low and high pH values have fundamentally different phase compositions and structures. The high-temperature annealing of hy drous zirconia xerogels is useful for manufacturing materials with controlled surface fractal dimensions.
