摘要

制备了组成为(Ag/sub 2/O)/sub x/(P/sub 2/O/sub 5/)/sub 1-x/的二元磷酸银玻璃样品，并在频率、组成和温度范围内测量了它们的交流电导率。可以观察到，交流电导率在低频(低于1khz)时逐渐增加，但在高频(高于10khz)时迅速增加。电导率高达10/sup -5/ Scm/sup -1/，这取决于样品的组成、频率和温度。电导率随Ag/sub 2/O的摩尔分数几乎呈线性增加，并随温度升高而增加。符合Arrhenius图，得到了0.41 ~ 0.46 eV的活化能。

AC conductivity of binary silver phosphate glasses

Samples of binary silver phosphate glasses with composition (Ag/sub 2/O)/sub x/(P/sub 2/O/sub 5/)/sub 1-x/ have been prepared and their AC electrical conductivities measured over a range of frequency, composition and temperature. It is observed that AC conductivity increases very gradually at low frequency (below 1 kHz), but rapidly at higher frequency (above 10 kHz). Conductivity as high as 10/sup -5/ Scm/sup -1/ has been observed depending on the composition, frequency and temperature of the samples. The conductivity increases almost linearly with the mole fraction of Ag/sub 2/O, and also increases with temperature. The Arrhenius plot is obeyed and an activation energy of 0.41 to 0.46 eV has been obtained.
