Description: Abstract Mit steigender Reduktionstemp. (470‐870 K) und zunehmendem Ni‐Austauschgrad (10‐54 Äquiv.‐%) verringert sich die Metalldispersität. Eine Teilchenvergrößerung nach Reoxidation (470 K) und Reduktion (Regeneration) der NiNaY‐Proben ist auf Aggregation der Oxidteilchen und auf das Sintem des Metalls im Reduktionsprozeß zurückzuführen.
