V.M. Buznik made a significant contribution to the quantum theory of ionic crystals - the approaches developed by him made it possible to calculate a set of micro- and macroparameters. This opened up the prospect of understanding the radio-spectral, spectroscopic, structural, energy characteristics of not only model systems, but also important crystalline materials of structural types of rutile, fluorite, and perovskite.
He proposed methods for obtaining non-empirical interatomic potentials that are effective for calculating multicomponent crystals and disordered systems, including glass. His numerous and systematic studies formed the basis of nuclear resonance spectroscopy of ionic solids, which helped to deepen the understanding of the nature of the microscopic structure and established the relationship of spectral parameters with the most important characteristics (binding energy, melting point, microhardness, etc.).
Under his leadership, work was carried out for the first time to study the topological structure of disordered solid fluorides (solid solutions, glasses) using nuclear magnetic resonance (NMR) methods, which made it possible to obtain unique information about their structure and to associate structural factors with ion-transport characteristics. Due to the achieved results, the role of structural factors and technological processes in the search and production of glass materials with high fluoride-ionic conductivity was established.
