Claim:
1. A process for preparing transition metal hydroxides having a mean particle diameter in the range from 6 to 12 μm (D50), the process comprising: combining, in a stirred vessel, a solution of a transition metal salt with a solution of an alkali metal hydroxide to prepare an aqueous suspension of transition metal hydroxide; continuously withdrawing a volume of the suspension from the stirred vessel and supplying to at least one separately powered compartment; continuously introducing, in the at least one separately powered compartment, a mechanical power in the range from 50 to 10,000 W/l in each case, based on the volume of the suspension; and then recycling the volume from said at least one separately powered compartment back into the stirred vessel.
