Nanocrystalline Mg2Ti2Zr5O16 ceramic is successfully synthesized through the modified combustion technique.The surface morphological analysis carried out with Scanning Electron Microscope (SEM) displays that the materal is highly sintered with minimum pores. The energy-dispersive spectrometry (EDS) shows that the material consist of only elements in the stoichiometric concentration and no impurities are present. The dielectric studies indicates that the material processes a high dielectric constant of 170 at 1 MHz and 750 °C. The conductivity is found to increases with temperature and the maximum value of conductivity is 3.4 x 10−2 S/m at 650 °C. The electrical properties of the sample is evaluated using the Z-View software. The sample acquired grain and grain boundary activation energies of 0.11 eV and 0.26 eV, respectively. The high ionic conductivity of the material suggests that, it can be used as electrolyte in solid oxide fuel cells.
