A study on the electrolytic properties of $CaF_2$ crystals with $YF_3$ addition

crystals were grown with various growth rates by Bridgman method, and the electrical properties of these were studied to examine the changes of ionic conductivities with growth rates by AC Impedance Analyzer. As the growth rates were higher, crystals were grown to polycrystals from single crystal. And as grain boundaries and various defects were altered, the ionic conductivities were changed dramatically. added to for disorderizing structure and improving the number of carriers and vacancies in crystals. Then crystals were gained. And the ionic conductivities of crystals were investigated with addition. The ionic conductivities of and crystals with temperatures were compared. In addition, the effects of clusterings and defects on the electrical properties of solid electrolytes were researched.
