摘要

本研究旨在研究温度和频率对(AgPO3)1-x(Ag2SO4)x离子导电玻璃体系交流电导率的影响，其中x = 0.00, 0.10, 0.15, 0.20和0.25。使用不同的技术对不同的样品进行了结构表征。在较低的频率范围内，总电导率随频率和温度的增加而呈幂函数关系，与频率的依赖关系基本不变。指数S的观测值在某种程度上与频率有关，当x = 0.15时，指数S随温度的升高从1.3降至0.2。直流至色散区的截止频率ωc随温度升高而升高。ωc值与其他值在同一范围内。总电导率σtot(ω)为Arrhenius型热活化。

Structural, Thermal and Electrical Properties of Ionic Conductors (AgPO3)1-x(Ag2SO4)x Glass Systems

This study aims to investigate the effect of temperature and frequency on the ac conductivity of ion conducting glasses systems of (AgPO3)1-x(Ag2SO4)x, where x = 0.00, 0.10, 0.15, 0.20 and 0.25. Structural characterisation was examined in different samples using different techniques. At lower frequency range, the frequency dependence of the total conductivity was nearly constant and then followed a power relation as frequency and temperature increased. The observed values of the exponent S were somehow frequency-dependent and decreased with increasing temperature from 1.3 to 0.2 for the composition when x = 0.15. The cutoff frequency from dc to the dispersive region, ωc, increased with temperature. In addition, ωc values were within the same range as other values. Total conductivity σtot(ω) was found to be thermally activated of the Arrhenius type.

期刊介绍： IJMMP publishes contributions on mechanical, electrical, magnetic and optical properties of metal, ceramic and polymeric materials in terms of the crystal structure and microstructure. Papers treat all aspects of materials, i.e., their selection, characterisation, transformation, modification, testing, and evaluation in the decision-making phase of product design/manufacture. Contributions in the fields of product, design and improvement of material properties in various production processes are welcome, along with scientific papers on new technologies, processes and materials, and on the modelling of processes.
