Summary: | Sr- and Mg-doped lanthanum gallate which exhibits high ionic conductivity was synthesized by a citrate method using industrial raw materials. X-ray diffraction analysis revealed that the powder by a citrate method was single-phase. Electron probe micro analysis (EPMA) showed that the sintered body which was formed by synthesized powder by a citrate method and fired at 1723 K for 6 h had inhomogeneous texture caused by segregation of Sr and Ga elements. Scanning electron microscope (SEM) images and densimetry revealed that the sintered body synthesized by a citrate method had high density, the sintered bodies synthesized by a citrate method had much higher oxide ion conductivity than those by a solid state reaction method. |
