    摘要： A method of making cermet inert anodes for the electrolytic production of metals such as aluminum is disclosed. The method includes the step of spray drying a slurry comprising ceramic phase particles and metal phase particles. The resultant spray dried powder, which comprises agglomerates of both the ceramic phase and metal phase particles, may then be consolidated by techniques such as pressing and sintering to produce a cermet inert anode material. The ceramic phase may comprise oxides of Ni, Fe and at least one additional metal selected from Zn, Co, Al, Li, Cu, Ti, V, Cr, Zr, Nb, Ta, W, Mo, Hf and rare earths. The metal phase may comprise Cu, Ag, Pd, Pt, Au, Rh, Ru, Ir and/or Os. The consolidated cermet inert anode material exhibits improved properties such as reduced porosity. The cermet inert anodes may be used in electrolytic reduction cells for the production of commercial purity aluminum as well as other metals.

    摘要： 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 that includes particles of zirconia stabilized by yttria covered with nickel salt; e) calcining under oxidating conditions the solid to cause the formation of a solid that includes particles of zirconia stabilized by yttria covered with nickel oxide; and f) treating with hydrogen the solid obtained in step (e) to reduce the nickel oxide to metal nickel and obtain the nickel cermet.
