Аннотация:We compare ionic conductivity in zirconium hydrogen phosphate samples with NASICON structure prepared by various methods. Hydrothermal and hydrothermal/ultrasonic treatment reduces the crystallite size and increases ionic conductivity in HZr2(PO4)(3) center dot nH(2)O samples at low temperatures. At high temperatures, the conductivity of the anhydrous phase HZr2(PO4)(3) is higher in the material prepared by ion exchange. Ultrasonication does not considerably improve the properties of hydrothermally prepared samples.
