“…The part III of the temperature de pendence of the conductivity (AH = 0.34+0.01 eV) is probably connected with a short-range motion of nonbridging fluoride ions. The theoretically calculated enthalpy for this motion is 0.29 eV [7].…”

“…As heavy metal fluorides are usually good fluoride ion conductors [7,8], heavy metal fluoride glasses and fibers based on ZrF4, PbF 2 or ZnF 2 are prospective materials also for a development of glassy superionics and of superionic fibers [9][10][11]. The preparation of glassy fluoride superionics is technologically more simple and cheaper NaF ZBA 62 33 ---5 ---ZBLA 57 34 5 4 ---ZBLAN4 55 31 5 5 4 ZBLAN7 57 30 3 3 7 ZBLAN20 53 20 4 3 20 ZBISN30 30 20 10 l 0 ---30 ZBISN40 40 20 10 10 ---20 ZBISAN50 50 10 10 10 10 10 than the preparation of fluoride single crystals or ceramics.…”

“…Se han observado tendencias similares en CaF 2 , SrF 2 , BaF 2 , aunque muestran una conductividad menor a temperaturas más elevadas (2). Las soluciones sólidas isovalentes y heterovalentes basados en PbF 2 , son materiales interesantes para desarrollar electrolitos sólidos con una conductividad rápida de iones fluoruros a moderadas y a bajas temperaturas, debido a que generan tanto vacantes de F -como iones intersticiales de F - (11,(14)(15)(16). El dopaje con iones isovalentes altamente polarizables como el Sn 2+ , ha mostrado un extraordinario incremento en la conductividad en los cristales de PbF 2 , formando un conductor rápido de aniones PbSnF 4 (5-8).…”

“…Varios compuestos con estructura tipo fluorita presentan valores elevados de conductividad del ion flúor (4,(9)(10)(11). Esto se debe a que el átomo metálico forma una red cúbica centrada en las caras, y los átomos de flúor se encuentran ocupando todos los huecos tetraédricos; dejando por lo tanto, los huecos octaédricos desocupados, generando de esta manera una estructura bastante abierta que favorece la movilidad de los iones fluoruros (12,13).…”

“…The fast ionic conductivity is usually observed in the systems where a maximum of the liquidus occurs in the region of fluorite structured solid solutions. Among fluorite-structured PbF2-based heterovalent solid solutions, the fastest ionic conductivity is found for the PbF2:ScF 3 system [4,10]. Therefore, we have studied also the conductivity of BaF2:ScF3 solid solutions.…”
