| 发明名称 | Process for preparing transition metal hydroxides | ||
| 摘要 | The present invention relates to a process for preparing transition metal hydroxides with a mean particle diameter in the range from 6 to 12 μm (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. | ||

| 主权项 | 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. | ||
