Abstract
There are provided glass-ceramics having a high lithium ion conductivity which include in mol %:and contain Li1+X(Al, Ga)XTi2−X(PO4)3 (where 0<X<0.8) as a main crystal phases. There are also provided glass-ceramics having a high lithium ion conductivity which include in mol %:and contain Li1+X+YMXTi2−XSiYP3−YO12 (where 0<X≦0.4 and 0<Y≦0.6) as a main crystal phase. There are also provided solid electrolytes for an electric cell and a gas sensor using alkali ion conductive glass-ceramics, and a solid electric cell and a gas sensor using alkali ion conductive glass-ceramics as a solid electrolyte.
