Description
晶析において、ｐＨは、ｐＨコントローラにより水酸化ナトリウム水溶液の供給流量を調整することで制御され、変動幅は設定値の上下０．２の範囲内であった。得られたニッケルコバルトマンガン複合水酸化物粒子について、レーザー回折式粒度分布計（日機装株式会社製、マイクロトラックＭＴ３３００ＥＸＩＩ）を用いて、平均粒径の測定及び粒度分布を示す〔（ｄ９０−ｄ１０）／平均粒径〕値を算出した。その後、タップ密度を測定するため１２０℃で乾燥後、解砕しＪＩＳ Ｒ １６２８によりタップ密度を測定した。 In crystallization, the pH was controlled by adjusting the supply flow rate of the aqueous sodium hydroxide solution with a pH controller, and the fluctuation range was within the range of 0.2 above and below the set value. About the obtained nickel cobalt manganese composite hydroxide particle, the measurement of an average particle diameter and particle size distribution are shown using a laser diffraction type particle size distribution meter (the Nikkiso Co., Ltd. make, Microtrac MT3300EXII) [(d90-d10) / Average particle size] value was calculated. Then, in order to measure a tap density, after drying at 120 degreeC, it grind | pulverized and the tap density was measured by JISR1628.
