ABSTRACT:
Mixed metal oxides are prepared as catalyst materials by a method comprising high energy impact milling of a formulated mixture of powders to form a mechanically alloyed product and heat treating said product in an oxidizing atmosphere to form the desired compound. In a preferred embodiment a catalytic material is formed which has the general empirical formula ABO.sub.3 and a perovskite-type crystal structure.
