摘要

采用拉曼光谱、差示扫描量热法和电化学阻抗谱研究了（0.76LiClO4-0.24KClO4）eut共晶体系及其与纳米氧化铝粉的非均相复合材料在不同温度、相态和Al2O3浓度下的物理化学性质。Al2O3的加入提高了离子电导率，降低了活化能。拉曼光谱结果表明，由于高氯酸锂晶体相的破坏，氧化铝的加入导致了非晶相的形成。

The Raman Spectroscopy Study of the Binary Eutectic System (1 – x)(LiClO4–KClO4)–xAl2O3

The physical and chemical properties of the (0.76LiClO₄–0.24KClO₄)_eut eutectic system and its heterogeneous composites with nanosized aluminum oxide powder are investigated by Raman spectroscopy, differential scanning calorimetry, and electrochemical impedance spectroscopy at different temperatures, phase states, and Al₂O₃ concentrations. The Al₂O₃ addition increased the ionic conductivity and lowered the activation energy. It is shown by the Raman spectroscopy that the addition of aluminum oxide leads to the formation of an amorphous phase, due to the lithium perchlorate crystalline phase destruction.
