✦ Synopsis

Formation of boehmite sols from aluminium alkoxides was studied by X-ray diffraction, IRspectroscopy, DLS (Dynamic Light Scattering) and other methods. It was found that the distortion of the boehmite crystal lattice occurs under the electrolyte sol formation processes. The surface charges were evaluated to explain the observed changes in X-ray patterns and IR-spectra of the boehmite samples and the causes that bring about these changes. The influence of the peptizing process on ~-Al203 specific surface was also studied.
