摘要
Electrical conduction in substituted scheelite-type oxides was studied by way of electrochemical method. Many substituted samples based on CaWO4, CaMoO4, BaWO4, etc. showed the mixed phase, where enhanced electrical conduction was not observed. High oxide ion conduction was observed in Pb1-xLaxWO4+x/2 or Pb1-xLa2x/3WO4 having the scheelite-type tetragonal structure. The maximum conductivity is 4.2 x 10(-2) S cm-1 at 800-degrees-C for Pb0.8La0.2WO4.1. The oxide ion conduction was considered to be due to the interstitial oxide ions formed by substitution of Pb2+ by La3+. These results are discussed in relation to the crystal phases.
