  • Process for preparing transition metal hydroxides
    Patent number: 9630842
    Abstract: The present invention relates to a process for preparing transition metal hydroxides with a mean particle diameter in the range from 6 to 12 ?m (D50), which comprises combining, in a stirred vessel, at least one solution of at least one transition metal salt with at least one solution of at least one alkali metal hydroxide to prepare an aqueous suspension of transition metal hydroxide, and, in at least one further compartment, continuously introducing a mechanical power in the range from 50 to 10 000 W/l in a proportion of the suspension in each case, based on the proportion of the suspension, and then recycling the proportion into the stirred vessel.
    Type: Grant
