Abstract

Sm_1-xSr_xAlO₃ (0 ≤ x ≤ 0.5) powders synthesize with use of Samarium nitrate, Strontium nitrate, Aluminum nitrate and aspartic acid (fuel) by assisted combustion method and it heat at 550ËšC for 6 hours. The thermal decomposition, phase identification, surface morphology and ionic conductivity of the samples study with Thermal gravimetric Analysis./ Differential Thermal Analysis., X-ray diffraction, Scanning Electron Microscopy and four probe D.C. method respectively. The formation of Sm_1-xSr_xAlO₃ confirm with use of Fourier Transformer Infra-red studies. The weight gain and loss performance confirm with use of thermo chemical techniques. The nanoparticle size measure with High Resolution Transmission Electron Microscope studies. The synthesize materials show the reasonable ionic conductivity. These results indicate the assisted combustion method is a promising method to prepare nanocrystalline Sm_1-xSr_xAlO₃ for solid oxide fuel cell.
