The stability of silicon complexes formed in KF-KI-KCl-K2SiF6 and KF-KCl-KI-K2SiF6-SiO2 was studied using the density functional theory method. The calculations of the bond energy Si-F and Si-I were performed. Conclusions about the stability of silicon complexes containing different amounts of iodine ions in the inner coordination sphere were made. All oxyfluoride silicate complex compounds became extremely unstable when replacing fluoride with iodide ion.

This paper describes an experimental setup for the deposition of silicon dioxide in a nanoporous material. Nanoporous material was obtained from aluminum, 99.7 % purity. The matrix was impregnated in organic media containing tetraethoxysilane. The obtained product was analyzed using XRD while the diffusion of silicon dioxide was examined using scanning electron microscopy in combination with energy dispersive analysis. The characteristics of the filling of nanoporous materials by chemical precipitation from organic liquid media are considered. Electrophysical characteristics of the obtained composite were studied. Techniques are proposed for improving the occupancy rates of nanoporous inorganic systems with inorganic oxide components.This paper describes an experimental setup for the deposition of silicon dioxide in a nanoporous material.
