In a process for the manufacture of an agglomerated mixture comprising 30-95% by weight of highly dispersed metal oxides produced by flame hydrolysis and 5-70% by weight of inorganic opacifiers that have at least one absorption maximum in the range between 1.5 and 10 mm, selected from the group consisting or inorganic oxides and mixed oxides, carbides and nitrides wherein volatile metal compounds are initially flame hydrolyzed in a combustion zone where they react with a flame to form highly dispersed metal oxides and are then agglomerated in an agglomeration plant, the improvement comprising the steps of: continuously mixing said inorganic opacifiers with said flame-hydrolyzed metal oxides in the aforesaid percentages in a region in which the flame-hydrolyzed metal oxides are still in the form of primary particles; and coagglomerating said inorganic opacifiers while agglomerating said metal oxides subsequent to the flame hydrolysis.
