Ammonia → Nickel cobalt aluminum hydroxide

In this way, the reaction was conducted for 48 hours while continuously adding the aqueous solution of mixture of nickel nitrate, cobalt nitrate and aluminum nitrate, the aqueous ammonia and the aqueous solution of sodium hydroxide to the reactor. During the reaction, the concentration of ammonia in the reaction mixture (slurry) in the reactor was kept within a range from 1.0 to 1.3 mol/L and the reaction temperature was kept at 30° C.±1° C. with a temperature controller, After the completion of the reaction, the slurry in the reactor was filtered, washed with water and dried to provide a powder of nickel cobalt aluminum hydroxide.
