| description | Hollow spheres structures of La<sub>0.7</sub>Sr<sub>0.2</sub>Ca<sub>0.1</sub>Co<sub>0.9</sub>Fe<sub>0.1</sub>O<sub>3–δ </sub> (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. |
