Title:
SOLID ELECTROLYTE
Document Type and Number:
Japanese Patent JPS5642909
Kind Code:
A
Abstract:
ZrO2-Y2O3 solid electrolytes having a high strength and an excellent deterioration property so as to be durable for a long time, comprised mainly of cubic crystal and monoclinic crystal or cubic crystal, monoclinic crystal and tetragonal crystal, wherein an average grain size of monoclinic crystal or tetragonal crystal is not greater than 2 mu m and a ratio of the intensity of the monoclinic (III) X-ray diffraction line to that of the cubic (200) line is 0.01-2.5. In the case of solid electrolytes comprised mainly of cubic crystal, monoclinic crystal and tetragonal crystal, the following definition is necessary. A ratio of the intensity of the tetragonal (200) X-ray diffraction line to that of the cubic (200) line is not greater than 1.0.
