Etude de la conduction ionique de verres a base de ZrF4

A high-resolution 19F NMR spectroscopic study of barium fluorozirconate glasses and related crystals

“…The latter application, in particular, has attracted significant technological interest as these glasses can have even lower optical losses than silica in the important telecommunication window [4]. In addition, the high fluorine ion conductivity of these glasses has also led to curiosity in them as solid electrolytes [5].…”

Anion-conducting fluoride and oxyfluoride glasses

“…The pioneering study on the anionic conductivities of fluorozirconate glasses 2 7 LaF 3 (T g = 320 8C). Measurements of the transport numbers demonstrated that the glasses possess unipolar fluoride-ionic conductivities (the transport numbers of the electron transport are <10 73 ).…”

“…The discovery 1 of the anionic (fluoride) conductivity of fluoroberyllate glasses of the BeF 2 + MF (M = Na or Cs) type and fluorophosphate glasses of the Ba(PO 3 ) 2 + MF 2 (M = Ca, Sr, Ba or Mg) type and, particularly, the preparation of fluorozirconate glasses in systems involving ZrF 4 and BaF 2 and investigations 2 of their transport properties gave impetus to extensive studies of fluoride transport in glassy materials. Glasses possessing high F 7 ionic conductivity constitute a special class of anion-conducting solid electrolytes.…”

Enhancement of bromide ion conductivity in lanthanum oxybromide based solids by doping divalent zinc ion with high electronegativity

“…Solid electrolytes are functional materials where only a single ion species can migrate macroscopically as the charge carrier. Until now, many ions having relatively small ionic-size (Li + [1][2][3], Na + [4][5][6], F − [7][8][9], O 2− [10][11][12] etc.) are known to conduct in the solid lattice smoothly, and some solid electrolytes showing high conductivity are indispensable materials for electronic devices, such as batteries and chemical sensors.…”
