Date Apr. 20, 1989.Method for the production of catalytically active mixed phases in powder form from precursors which contain the elements of the mixed phase and are treated thermally and mechanically. The precursor or precursors contained in a solution or suspension are applied to heated surfaces of moving heat carrying bodies and precipitated and dissociated on them with evaporation of the solvent or of the liquid component of the suspension. The mixed phase formed on the heat carrying bodies is removed from the heat carrying bodies and then, to prepare it for further use, it is crushed.
