The invention relates to a method for producing a multiple-phase multi-metal oxide material that contains Mo, V, Cu and, optionally, other elements. According to the invention, at least one phase is separately pre-formed and is dispersed in a plastically deformable precursor material of another phase. The mixture is then dried and calcined. The multi-metal oxide material is suited for use as an active material of catalysts for catalytically oxidizing organic compounds in the gas phase, in particular, for oxidizing acrolein into acrylic acid.
