Description
Apatite lanthanum silicate is an oxygen ionic conductor with high conductivity. In this paper, research the effects of Gd and Zn double doping in La9.33Si6O26+x. Synthesis La9.33GdxSi5ZnO25+3x/2 (x = 0.2, 0.4, 0.6, 0.8) by Sol-gel Self combustion method, Characterization of the synthesized phase and electrical properties by X-ray diffraction, Scanning electron microscopy and Electrochemical workstations. The results show that doping can effectively improve the conductivity, La9.33Gd0.2Si5ZnO25.3has best conductivity that reach 1.49×10−3S/cm in 500°C. (paper)
