| Abstract: The air-solid interface reaction of Ce, Lu with K10H3[Gd(SiMo4W7O39)2] through chemistry-heated permeation is reported for the first time. The permeated complex is characterized by ICP and the result shows that the minimum Ce, Lu can permeate into the inner sphere of K10H3[Gd(SiMo4W7O39)2]. The IR, XRD patterns give the evidence that after permeation the complex still keeps the Keggin structure, however, its crystal structure is different from the complex before permeation. The conductivity of the permeated complex has been measured with the four-electrode method and the data show that the conductivity of the complex after permeation is 106 times higher than that of the sample before permeation and reaches 4.846×10-1S·cm-1. These indicate that the permeated complex is a good solid electrolyte and further applications are also expected. |
