    Abstract: The invention relates to a method for producing transition metal carbonates having an average particle diameter in the range from 6 to 19 µm (D50), characterized in that at least one solution of at least one transition metal salt is combined with at least one solution of at least one alkali metal carbonate or alkali metal hydrogen carbonate in a stirring vessel, whereby an aqueous suspension of transition metal carbonate is produced. The invention is also characterized in that, in at least one further compartment, a mechanical power in the range from 50 to 10000 W/I is continuously applied to a fraction of the suspension, with respect to the fraction of the suspension, and that the fraction is subsequently fed back into the stirring vessel.
