Abstract:
The structure of amorphous Al2O3 samples, prepared by anodic oxidation
of aluminium foils, was investigated by X-ray and neutron diffraction.
The partial pair correlation functions were determined from computer
simulation of the structure using the Reverse Monte Carlo method with
the result that amorphous Al2O3 is built up by AlO4 tetrahedra with
corner sharing oxygen atoms. Pores in the material were characterized by
neutron small-angle scattering.
