- W2054505941 abstract "A series of oxyhalogenide 30 SiO2–55 PbO–15 Pb(F1−xClx)2 (0 ≥ x ≥ 1) glasses belonging to the quaternary SiO2PbOPbF2PbCl2 system are prepared. A study of the electrical properties of these materials allows to prove the existence of a mixed mobile ion (MMI) effect in these anion-conducting glasses over the whole mixing range of the mobile ions. A mathematical treatment using the effective medium aproach (EMA) is applied to these materials by taking into consideration the pairing of unlike ions and partial blocking of transport paths by these pairs. It is proposed that the i (i = F, Cl) mobile ions can jump from a given site following z different directions through regions of ii-type, jj-type or ij-type with self-(D), foreign-(D), and mixed (D) diffusion coefficients respectively. A satisfactory fitting between the calculated and experimental values of conductivity is obtained as a function of substitution rate and temperature. It is concluded that the ionic transport in the oxyhalogenide glasses studied takes place following preferential pathways.Aus dem quarternaren System SiO2PbOPbF2PbCl2 werden Glaser der Reihe 30 SiO2–55 PbO–15 Pb(F1−xClx)2 prapariert. Leitfahigkeitsuntersuchungen uber den gesamten Mischungsbereich belegen, das in diesen anionisch leitenden Glasern ein Mischioneneffekt der beweglichen Anionen auftritt. Eine mathematische Modellierung dieses Verhaltens gelingt mit einem Effektiv-Medium-Ansatz (EMA). Hierbei werden die Paarbildung von ungleichen Ionen sowie ein teilweises Blockieren von Transportpfaden durch diese Paare berucksichtigt. Dabei wird angenommen, das Ionen der Art i (i = F, Cl) sich durch Regionen vom ii-, jj- oder ij-Typ bewegen, die jeweils durch die Selbst-(D), Fremd-(D) und Mischdiffusionskoeffizienten (D) gekennzeichnet sind und das von einem Platz Sprunge in z verschiedene Richtungen erfolgen konnen. Es wird eine gute ubereinstimmung von berechneten und gemessenen Werten der Leitfahigkeit als Funktion von Austauschgrad und Temperatur erreicht. Die Ergebnisse lassen darauf schliesen, das der Ionentransport in den untersuchten Oxyhalogenidglasern uber Vorzugspfade erfolgt." @default.
