Abstract: | The possibility of synthesizing sulfide-conducting solid electrolytes in the CaYb2S4-Y2S3 quasibinary system is tested for the first time. The system is characterized by the X-ray diffraction analysis and the electron microscopy. The total conductivity of specimens is found by the conductometric method. The ionic and electronic transport numbers are determined based on the modified versions of the emf method and the Hebb-Wagner polarization method. The possible mechanism of defect formation is discussed. |
