Abstract: The present invention provides a nickel cermet, which includes: 35% to 70% by weight of a nickel phase, and 65% to 30% by weight of zirconium oxide phase, wherein the zirconium oxide is stabilized in cubic form by 5 to 20 moles of yttrium oxide for each 100 moles of said zirconium oxide, and the metal nickel and zirconium oxide phases, upon X ray diffraction analysis are distinct and homogeneously distributed; and is prepared by a process that includes: a) dispersing zirconia stabilized by yttria having a particle size of between 1 and 40 &mgr;m , in demineralized water to prepare a suspension; b) dissolving a hydrosoluble and thermodecomposable nickel salt in demineralized d water to prepare a solution; c) mixing the nickel solution with the suspension and homogenizing the resulting dispersion by magnetic stirring for a time of between 5 and 40 minutes; d) eliminating the water from the dispersion by a system capable of operating without, or almost without, decomposition phenomena to obtain a solid th

Abstract: Nickel cermet consisting of from 35 to 70% by weight of a metal nickel phase and 65 to 30% by weight of a zirconium oxide (zirconia) phase stabilized in cubic form by 5 to 20 moles of yttrium oxide (yttria) for each 100 moles of zirconium oxide, the two phases, upon X ray diffractometric analysis, being distinct and homogeneously distributed, characterized in that it is obtained by a process comprising the following steps:
