A nickel cermet containing a metal nickel phase and an yttria stabilized zirconia phase, is prepared by a process comprising: preparing a suspension of the zirconia in demineralized water; preparing a solution of a nickel salt in demineralized water; mixing the nickel solution and the zirconia dispersion; eliminating the water from the mixture to obtain a solid containing particles of the zirconia covered with the nickel salt; calcining the solid under oxidizing conditions to form particles of the zirconia covered with nickel oxide; and reducing the nickel oxide with hydrogen to nickel metal.
