Ceramic Synthesis and Ionic Conductivity of Nanofluorides (Ce1–xPrx)0.95Sr0.05F2.95 with a Tysonite Structure Prepared by Thermal Decomposition of Trifluoroacetate Precursors
Nanosized powders (Ce1–xPrx)0.95Sr0.05F2.95 (x = 0, 0.5, 1) with a tysonite structure (sp. gr. \(P\bar {3}c1\)) are synthesized by the thermal decomposition of trifluoroacetate precursors in an inert environment. The ceramics are cold pressed, and their X-ray and conductometric properties are studied. It is found that the mixed composition nanoceramics (Ce0.5Pr0.5)0.95Sr0.05F2.95 (x = 0.5) demonstrate a higher electrolytic characteristics compared to the compositions with x = 0 and 1. The value of its ionic conductivity is σdc = 6.5 × 10‒3 S/cm at 500 K. The cation composition of the studied solid electrolyte (Ce0.5Pr0.5)0.95Sr0.05F2.95 is promising for further optimization of the ceramic synthesis process and application in various electrochemical devices.
