Synthesis of Nano-Sized Solid Electrolyte PrSryF and the Effect of Heat Treatment on the Ionic Conductivity of Fluoride Nanoceramics
Solid electrolyte nanoceramics Pr Sr y F ( y = 0.03, sp. gr. ) were obtained by high-energy milling of melt-grown crystals, followed by cold pressing. The phase composition, microstructure, morphology, and electrical properties of nanoceramics were studied using X-ray diffraction analysis, electron...
