ABSTRACT

The influence of nanosized aluminum oxide powder on the molecular relaxation properties of nitrate ion in the melt of a 0.42LiNO₃–0.58KNO₃ eutectic mixture was studied by vibrational spectroscopy. It is shown that the presence of nano-Al₂O₃ leads to a significant change in the microstructure of the melt and a change in the nature of the elementary dynamic interactions of the particles in them
