The Effect of the Nanosized Oxide Filler on the Structure and Conductivity of Composite (1 – x )(LiClO 4 –NaClO 4 )– x Al 2 O 3

The physicochemical properties of the eutectic system 78.2LiClO 4 –21.8NaClO 4 and its heterogeneous composites with nanosized alumina are studied at different temperature, phase state, and Al 2 O 3 concentration using the methods of Raman spectroscopy, differential scanning calorimetry (DSC), and impedance spectroscopy. The addition of Al 2 O 3 increases the ionic conductivity and decreases the activation energy. The Raman spectroscopic studies have shown that the addition of alumina leads to the formation of the amorphous phase as a result of destruction of the crystalline phase of sodium perchlorate.
