Abstract

Un cermet di nichel contiene 35-70% in peso di una fase di nichel metallico e 65-30% in peso di una fase di ossido di zirconio (zirconia) stabilizzato nella forma cubica con ossido di ittrio (ittria), le due fasi, all'esame diffrattometrico ai raggi X, essendo distinti ed omogeneamente distribuite ad un livello inferiore a 1 ?m.Questo cermet di nichel viene ottenuto preparando una soluzione acquosa contenente un sale termodecomponibile di zirconile, ittrio e nichel ed un idrossiacido o amminoacido organico, o un acido poliacrilico; eliminando l'acqua dalla soluzione in condizioni di assenza o sostanziale assenza di fenomeni di decomposizione, per separare un solido poroso; calcinando il solido poroso e riducendo con idrogeno il prodotto della calcinazione.Il cermet di nichel così ottenuto è utile quale materiale anodico per celle a combustibile ad ossidi solidi (SOFC).
