Abstract (en)

[origin: WO9908788A1] The invention relates to a method for producing multi-metal oxide masses containing Mo, V, Cu and at least one of the elements W, Nb, Cr and Ce. In this method, a solid component with fine particles is formed and incorporated, at low temperature, in an aqueous solution of parent compounds of the residual multi-metal oxide constituents. The mixture is dried and then burnt.
