N2 - © 2015 Advanced Study Center Co. Ltd.Solid solutions of ternary ZrO2-HfO2-Y2O3 system are the perspective materials to replace conventional yttria-stabilized Zirconia materials in electrochemical applications due to higher thermal stability and lower input of electronic conductivity at low oxygen partial pressures. Samples with 8 mol.% Y2O3 and HfO2 content from 5 to 20 mol.% were manufactured from nanosized precursors synthesized by sol-gel reverse co-precipitation technique. The structure of the samples was studied, particle size and phase composition were the points of essential interest. Impedance spectroscopy data provide the opportunity to separate grain and grain boundary inputs into the integral ceramics conductivity, these data were used to consider the grain boundary phase features. The conductivity dependence on sample chemical composition was determined.
