Electronic Conductivity in Solid CaF2 at High Temperature

“…[2] and values of ce ~ from Eq. [3] with aca = I. Only currents measured on the plateau of the current voltage curve yielded consistent values of tion.…”

“…(r e --" O" e' k aC----~ / [3] Polarization experiments on cells of type (II) where the inert iron electrode is made negative aIso yield electronic conductivity Fe (s) ICaF2 (s) lCa-Bi (1) (II) xca = 0.25 Under reducing conditions, the steady-state current of Cell (iI) at various applied voltages is given by i = ~e" exp --1 [4] FG where ce" is the electronic conductivity of CaP2 whose Ca activity is the same as that for Ca-Bi (2ca = 0.25).…”

“…Calcium fluoride has proven to be a useful solid electrolyte for high temperature emf studies (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20). A review has been given by Tretyakov and Kaul (21).…”
