Abstract: The relation between the broadening of X-ray diffraction peaks and their structure factor, for γ-and η-Aluminas, was studied. Comparison showed that the structure factor of the broad peaks result primarily from the Aluminium atoms. Thus, The structue imperfection of γ-and η-Aluminas is interpreted in terms of incomplete rearrangment of Aluminium atoms.

Key words: Structure of activated aluminas, Broadening of diffraction lines
