    Abstract: PURPOSE: Ceria composition is provided to enable low temperature sintering of ceria electrolyte for high temperature sensor or solid oxide fuel cell by adding lithium salt with a low melting point and/or volatility into a material in a ceria system or additionally adding bismuth oxide. CONSTITUTION: A ceria composition is composed of ceria or metal doped ceria, and lithium salt. The lithium salt occupies more than 0 weight% but less than 50 weight% among the ceria composition. The lithium salt is lithium carbonate, lithium hydroxide, or lithium nitride. The ceria composition additionally contains bismuth oxide. A sintering body is a sintering body of the ceria composition which comprises ceria or metal doped ceria, lithium carbonate, and bismuth oxide. The ceria composition contains lithium carbonate with more than 0 weight% but more or less than 5 weight% and bismuth oxide with more than 0 weight% but less than 10 weight% in the sintering body. A ceria complex electrolyte powder is a calcined body of the ceria composition. The ceria composition is composed of ceria or metal doped ceria, and lithium salt and the lithium salt occupies more than 0 weight% but less than 50 weight% in the calcined body.
