Correlation between the fluorine ion conductivities of Sr1−xRxF2+x (CaF2 type) and R1−ySryF3−y (LaF3 type) crystals in the SrF2–RF3 systems (R = La–Nd)
Abstract:
The “conductivity logarithm–composition” correlation logσdc(x)=ax+b has been revealed for the strongly nonstoichiometric fluorite Sr1−xRxF2+x (x is the RF3 molar fraction, 0.15 ⩽x⩽ 0.47) and tysonite R1−ySryF3−y (y is the SrF2 molar fraction, y=1−x, 0.85 ⩽x⩽ 0.97) phases in the SrF2–RF3 systems (R = La, Ce, Pr, Nd). The conductivity σdc of the eutectic 70LaF3 + 30SrF2 (mol %) composite fits well with the dependence logσdc(x) for the nonstoichiometric Sr1−xLaxF2+x and La1−ySryF3−y phases.
