THE INFLUENCE OF NANO-SIZED OXIDE FILLER ON THE STRUCTURE AND CONDUCTIVITY OF COMPOSITE (1–x) (LiClO4 –NaClO4) + xAl2O3

The physicochemical properties of the eutectic system 78.2LiClO4-21.8NaClO4 and its heterogeneous composites with nanosized aluminium oxide powder at various temperatures, phase states and concentrations of Al2O3 were studied by methods of Raman spectroscopy, differential scanning calorimetry (DSC) and impedance spectroscopy. The addition of Al2O3 leads to an increase in ionic conductivity and a decrease in activation energy. By the method of KRS spectroscopy it is shown that the addition of aluminum oxide leads to the formation of an amorphous phase due to the "destruction" of the crystalline phase of sodium perchlorate.
