Popis:	The principle of spark plasma ceramics sintering method is presented, its advantages and disadvantages are discussed. Li+ ionic conductor Li3xLa2/3–xTiO3 (x = 0.1) and oxygen ionic conductor CeO2-20 mol% Sm2O3 nanoceramics have been prepared using this method. Electrical properties of the obtained ceramics were measured in the broad frequency range of 10 Hz to 3 GHz and temperature interval from 300 K up to 800 K. Ionic conductivities inside grains and in the grain boundaries have been separated from impedance spectra.DOI: http://dx.doi.org/10.5755/j01.ms.19.3.2403
