Abstract
The mechanical strength of stabilized zirconia is improved without lowering the ion conductivity by providing a solid electrolyte comprising stabilized zirconia and a metal oxide dispersed within grains or grain boundaries of stabilized zirconia, the metal oxide having an average submicron particle size and stabilized zirconia having an average particle size larger than 1 micron, typically larger than 10 .mu.m or even 100 .mu.m.
