The complex physicochemical investigation of the morphological parameters of boehmite nanoparticles and their agglomerates has been carried out. It is shown that a complex approach to the nanoparticle analysis can resolve the contradictions and to increase the reliability of measurement results. The possibilities of the method of small-angle X-ray scattering for the characterization of nanoparticle with isometric shape have been demonstrated. The features of the dynamic light scattering method in the analysis of lamellar nanoparticles agglomerates are considered.

Keywords: boehmite, nanoparticles, hydrothermal synthesis, particle morphology, particle size, size distribution, agglomerates, atomic force microscopy, scanning electron microscopy, dynamic light scattering, X-ray diffractometry, small-angle X-ray scattering, adsorption-desorption gas analysis (BET method).
