Electrical Conductivity in Alkali Iron Phosphate Glasses

摘要：

　　The electrical properties of 10M2O-36Fe2O3-54P2O5 (M=Li,Na and K) glasses were studied in the temperature range from 323 to 573 K.Non-linear Arrhenius behavior was observed for all the samples examined.It was shown that in both high-and low-temperature ranges,the replacement ofLi,Na and K would result in decreases in both the dc conductivity and the activation energy.Analysis of the relationship of the parameters included in the Arrhenius equation,activation energy and the pre-exponential factor for each sample,preliminary explanations for these experimental phenomena have been presented.
