Hollow spheres structures of La0.7Sr0.2Ca0.1Co0.9Fe0.1O3–δ LSCCT have been synthesized via hydrothermal method using carbon spheres as template. The structure and electrical conductivity of obtained samples are characterized by X-ray diffraction XRD, scanning electron microscope SEM, transmission electron microscope TEM and direct current DC four-probe method respectively. The results show that hollow spheres structures of LSCCT with the mean particle size of 0,9 - 1,2 μm is single perovskite. The electrical conductivity of the samples is higher than 100 S-cm from 600 to 800 ℃ and can meet the demand of the electrical properties for the cathode materials.
