Abstract

In the present work, La0.6Sr0.4CoO3-δ (LSC) material is prepared with the aid of carbon nanotubes (CNTs) as dispersant and is characterized by thermal gravimetric analyzer (TGA), X-ray diffractometer (XRD), scanning electron microscope/energy dispersive X-ray (SEM/EDX) spectrometer and BET instrument. Decomposition of unwanted materials in the as-synthesized powder were completed at 600 °C and single LSC perovskite phase was formed at 900 °C. The calcined powder with surface area of 1.95 m2/g and agglomeration index of 33.71 is made up of homogeneous with almost identical shape of particles. All elements of the single LSC perovskite phase are close to their nominal mole fraction.
