Abstract: Provided is a method for preparing nickel-aluminum alloy powder at low temperature, which is simple and economical and is capable of solving the reactor corrosion problem. The method for preparing nickel-aluminum alloy powder at low temperature includes: preparing a powder mixture by mixing nickel powder and aluminum powder in a reactor and adding aluminum chloride into the reactor (S1); vacuumizing the inside of the reactor and sealing the reactor (S2); and preparing nickel-aluminum alloy powder by heat-treating the powder mixture in the sealed reactor at low temperature (S3).

Abstract: 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.
