Abstract

Copper-ion conducting glasses were prepared in the system (CuI,CuCl)-Cu/sub 2/O-MoO/sub 3/ using a rapid quenching technique. These glasses have high ionic conductivities at room temperature in the range of 10/sup -4/ to 10/sup -2/ S-m/sup -1/, and the conductivities increase with increasing CuI content but decrease with increasing CuCl content. The increase in the conductivity can be explained in terms of a decrease in the activation energy for conduction, and the activation energies for conduction are 0.19-0.39 eV. The electronic conductivities were measured by the Wagner polarization method. The ion transport numbers are 0.995-0.997, and it is shown that the transport number of Cu/sup +/ ions in these glasses is practically unity. The dielectric relaxation time is in the range of 3.7*10/sup -4/ to 1.2*10/sup -3/ s. The activation energies for ion jumping are 0.18-0.36 eV, and these are similar to those for conduction.<>

(CuI,CuCl)-Cu/sub 2/O-MoO/sub 3/体系中玻璃的电学性能

采用快速淬火技术，在(CuI,CuCl)-Cu/sub 2/O-MoO/sub 3/体系中制备了铜离子导电玻璃。这些玻璃在室温下具有较高的离子电导率，范围为10/sup -4/ ~ 10/sup -2/ S-m/sup -1/，电导率随CuI含量的增加而增大，随CuCl含量的增加而减小。电导率的增加可以用传导活化能的降低来解释，传导活化能为0.19-0.39 eV。用Wagner极化法测量了电导率。离子输运数为0.995 ~ 0.997，表明Cu/sup +/离子在这些玻璃杯中的输运数几乎是统一的。介电弛豫时间为3.7*10/sup -4 ~ 1.2*10/sup -3/ s，离子跃迁的活化能为0.18 ~ 0.36 eV，与传导的活化能相当。
