Abstract: Provided are a ceria-based composition including ceria or metal-doped ceria, lithium salt, and optionally, bismuth oxide, ceria-based composite electrolyte powder, and a sintering method and sintered body using the same. Particularly, the lithium salt is present in an amount more than 0 wt % and equal to or less than 5 wt %, and bismuth oxide is present in an amount more than 0 wt % and equal to or less than 10 wt %. It is possible to reduce sintering temperature by adding a low-melting point and/or volatile compound to a ceria-based material. In this manner, it is possible to ensure a high composite sintering density, for example, of 95% or more even at a temperature, for example, of 1000° C. or lower, which is significantly lower than the conventional sintering temperature of 1500° C. in the case of a ceria-based material alone.
