FIBROUS NICKEL AND METHOD FOR PRODUCING THE SAME

摘要

Provided is a method for producing fibrous nickel having a hexagonal close-packed structure including a first step for preparing a first solution by mixing nickel ions, a reducing agent, and a protectant in a solvent and a second step for heating the first solution at a temperature of 200°C or higher. The concentration of nickel ions in the first solution is within a range of 5 mmol/l to 20 mmol/l. Fibrous nickel having a hexagonal close-packed structure is obtained by this production method.
