Ceria-based composition including bismuth oxide, ceria-based composite electrolyte powder including bismuth oxide, method for sintering the same and sintered body made thereof
Provided are a ceria-based composition having an undoped or metal-doped ceria and an undoped or metal-doped bismuth oxide, wherein the undoped or metal-doped bismuth oxide is present in an amount equal to or more than about 10 wt % and less than about 50 wt % based on the total weight of the ceria-based composition, and at least one selected from the ceria and the bismuth oxide is metal-doped. The ceria-based composition may ensure high sintering density even at a temperature significantly lower than the known sintering temperature of about 1400° C., i.e., for example at a temperature of about 1000° C. or lower, and increase ion conductivity as well.
