Abstract
Description
粒径=6/(密度×比表面積)
邪魔板とオーバーフロー口を有する攪拌機構付きの有効容積4Lの反応槽に純水を入れてから炭酸ナトリウムと水酸化ナトリウムを添加して十分に攪拌し、炭酸ナトリウム濃度0.6mol/L、pH8.5の混合水溶液4Lを調製した。また、硫酸ニッケルを純水に溶解してニッケル濃度120g/Lに調整したニッケル水溶液と、水酸化ナトリウム及び濃度0.6mol/Lに調整された炭酸ナトリウムを含む添加用混合水溶液とを用意した。これらニッケル水溶液と添加用混合水溶液とを、前述の炭酸ナトリウムと水酸化ナトリウムとを含む反応槽内の混合水溶液に同時並行的且つ連続的に添加して混合させ、中和反応を行った。この時、両供給ノズル出口部からそれぞれ供給を行ったニッケル水溶液及び添加用混合水溶液は、各々供給先の反応槽内において乱流状態で混合されていた。
中和工程の反応時間を0.5時間に代えてそれぞれ0.2時間(実施例2)、1.0時間(実施例3)、1.5時間(実施例4)、2.5時間(実施例5)、3.5時間(実施例6)、5.0時間(実施例7)に調整した以外は実施例1と同様にして水酸化ニッケル粒子を得ると共に分析、測定を行った。
中和工程の反応時間を0.5時間に代えてそれぞれ0.1時間(比較例1)、6.0時間(比較例2)、10.0時間(比較例3)に調整した以外は実施例1と同様にして水酸化ニッケル粒子を得ると共に分析、測定を行った。更に、比較例2で得られた水酸化ニッケル粒子については、実施例1と同じ条件で酸化ニッケル微粉末を生成した。得られた酸化ニッケル微粉末の硫黄品位は70質量ppm、塩素品位は20質量ppm未満、ナトリウム品位は10質量ppm、比表面積は3.9m2/g、D90は0.87μmであり、硫黄品位とナトリウム品位が高いことが確認された。
中和反応時のpHを8.5に代えてpH8.0に調整した以外は実施例5と同様にして水酸化ニッケル粒子を得ると共に分析、測定を行った。
中和反応時のpHを8.5に代えてpH9.0に調整した以外は実施例5と同様にして水酸化ニッケル粒子を得ると共に分析、測定を行った。
撹拌回転数を600rpm(実施例9)、450rpm(実施例10)に調整した以外は実施例5と同様にして水酸化ニッケル粒子を得ると共に分析、測定を行った。上記の実施例1〜10及び比較例1〜4の水酸化ニッケル粒子の分析、測定結果を表1にまとめて示す。
Claims (4)
- 硫黄品位が0.4〜2.0質量%、塩素品位が20質量ppm以下、総アルカリ金属の品位が10質量ppm未満であることを特徴とする水酸化ニッケル粒子。
- レーザー散乱法で測定したD90が5〜60μmであることを特徴とする、請求項1に記載の水酸化ニッケル粒子。
