Abstract
A solid electrolyte having high electron conductivity and high oxide ion conductivity, which is composed of a sintered body consisting substantially of (a) an oxide of cobalt, (b) an oxide of at least one metal selected from strontium and lanthanum, and (c) an oxide of at least one metal selected from bismuth and cerium. This solid electrolyte is useful for selectively separating oxygen from a gaseous atmosphere having a high oxygen partial pressure into a gaseous atmosphere having a low oxygen partial pressure.
