Ionic Conductivity of Oxyfluoride

In this review we will consider anion-conductive fluorides and oxyfluorides because the occurrence of oxygen in these phases is an additional parameter that controls the defect structure of fluorite- and tysonite-like solid solutions by increasing the anion vacancies or

Because the easy oxygen introduction into fluorides changes essentially their conductivity some of such phases are rather sensitive to the gas atmosphere composition and could have different apphcations. For example LaFa and PbSnF4 were used as oxygen and moisture sensors [17-19].
