離が龍しく純度の高い製品が得られにくい。[Prior Art] A method is known in which a nickel compound is reduced with a reducing agent such as hypophosphorous acid or sodium borohydride in an aqueous solution system.
The shape is irregular, making it difficult to obtain a uniform, high-quality product.Also, hydroxides and oxides are replicated at the same time as the metal particles, making it difficult to separate them, making it difficult to obtain a highly pure product.

する手段として電磁石を用いて電磁分離し。[Problems to be Solved by the Invention] The present invention is characterized by six methods carried out in order to overcome the drawbacks of the conventional methods as described in the previous section. Using mild hydrazine as the main reducing agent and a small amount of sodium borohydride with strong reducing power to induce reduction, it is possible to produce submicron particles with two particle sizes and two well-shaped particles. Spherical particles can be obtained by adding dihydric alcohol as a shape control agent. Furthermore, electromagnetic separation is performed using electromagnets as a means of separating metals from hydroxides and oxides.
高純度(99%)の製品を得る方法を見いだした。We have found a way to obtain a product with high purity (99%).
[実施例] 次に実施例によって2本発明をさらに詳細に説明する。[Example] Next, the present invention will be explained in more detail by way of examples.

した。沈澱を冷凍乾燥器で乾燥させた。Thereafter, 50 ml of hydrazine was added with ethylene glycol added at a ratio of 1 while stirring with a magnetic stirrer. Then sprinkle a small amount of sodium borohydride powder. After stopping stirring for a while, the reduction reaction proceeds from the top of the beaker, and soon the reaction progresses violently, and the reaction progresses to the bottom of the beaker while generating hydrogen and ammonia gas.
After aging and reaction, the whole beaker is placed on an electromagnet for electromagnetic separation. Thereafter, the same liquid was separated using a centrifugal 1ill device. The precipitate was dried in a freeze dryer.
