Ionic Conductivity Measurements of LaF₃ Polycrystalline Powders

Abstract:

With the help of impedance spectroscopy, the complex impedances of three kinds of ultrafine LaF3 polycrystalline powders (industrial grade LaF3 polycrystalline powder, ultrafine LaF3 polycrystalline powder prepared with sol-gel technique, and ultrafine LaF3 polycrystalline powder prepared with microwave method) were measured, and their ionic conductivities were derived. It is found that the ionic conductivities of the industrial grade LaF3 polycrystalline powder and the ultrafine LaF3 polycrystalline powder prepared with microwave method are higher than that of the ultrafine LaF3 polycrystalline powder prepared with sol-gel technique.
