Abstract
Aluminium oxide systems were studied using a set of X-ray diffraction methods: Rietveld method, modelling of diffraction patterns of one-dimensionally disordered materials, modelling of fine dispersed substances, method of the radial distribution of electron density. Modelling of diffraction patterns of aluminium hydroxide and the curves of the radial distribution of electron density of oxides and hydroxides was carried out. Using the data of previous modelling, the real structure of aluminium hydroxides with different physicochemical properties and oxides obtained from them was studied. The results may be used in the analysis of any real object containing aluminium oxide systems, first of all nanometre-sized ones.
