A BaZr0.95Zn0.05Y0.1O3-α (BZY10) sample was successfully prepared by Pechini method

(PM) using metal nitrate-salts. The properties of the synthesized powder were determined using X-ray diffraction (XRD), scanning electron microscope (SEM), particles size analyzer and Fourier transform infrared (FTIR) Spectroscopy. FTIR analysis showed that decomposition of powder almost completed at 1100 ēC. Single phase of BaZrO3 was observed after calcination at T= 1300 ēC which is 200 ēC lower than that prepared by conventional solid state reaction (SSR) method. The loose particles size obtained from SEM and particle size analyzer was in the range 30−80 nm. The conductivity of the sample was 6.9 × 10-4 S cm-1 at T= 700 ēC in wet-nitrogen and the total activation energy, EaT was 0.79 eV.
