Abstract

La2In2-xAl2O(0 ≤ x ≤ 0.5) oxide ion conductor is synthesized with La(NO3)3, In(NO3)3, Al(No3)3and aspartic acid (fuel) by assisted combustion method which is heating at 550ËšC for 6 hours. X-ray diffraction analysis indicates that the orthorhombicstructure of La2In2-xAl2O9. Scanning electron microscopy is used to identify the surface morphology. The particle size of the synthesized product is measured by Scherrer equation and transmission electron microscope, its size 30 nm. The influence of the Al for Indium in La2In2-xAl2O9 of the phase transition has investigated by XRD studies. The formation of La2In2-xAl2O9 is confirmed by FTIR studies. The Arrhenius plot shows the ionic conductivity of La2In2-xAl2O9 on variation of temperature. This result indicates that assisted combustion method is a promising method to prepare nanocrystalline La2In2-xAl2O9 oxide ion conductor for solid oxide fuel cell.
