  • Nickel powder and method for producing nickel powder
    Patent number: 11850665
    Abstract: Provided is a nickel powder in which growth of the nickel hydroxide component into a plate-shaped crystal is suppressed in the oxide film, and the content of coarse particles containing plate-shaped nickel hydroxide is small, and provided is a method for manufacturing the nickel powder by a wet process in which the nickel powder can be produced further simply and easily. A nickel powder including: particles having a substantially spherical shape and a number average size of 0.03 ?m to 0.4 ?m; and an oxide film, on the particle surface, containing a basic salt of nickel hydroxide, wherein the content of coarse particles having a particle size of more than 0.8 ?m is 200 mass ppm or less, and the content of coarse particles having a particle size of more than 1.2 ?m is 100 mass ppm or less.
