Title:
NICKEL PARTICLES AND METHOD FOR MANUFACTURING NICKEL PARTICLES
Document Type and Number:
WIPO Patent Application WO/2024/070098
Kind Code:
A1
Abstract:
According to the present invention, nickel particles comprise a surface region including an alloy of a metal element M and nickel. The metal element M is at least one type of element selected from bismuth, copper, iron, and molybdenum. The content of the metal element M relative to the nickel particles as a whole is from 0.09 mass% to 15.8 mass%. When a region from a topmost surface to a sputtering depth of 5 nm by SiO2 conversion is measured in the depth direction of the nickel particles by X-ray photoelectron spectroscopy analysis, the value of X/Y is from 0.5 to 35, where X (at%) is the maximum value of the ratio of the number of atoms of the metal element M to the total number of atoms of the nickel element and the metal element M in said region, and Y (at%) is the ratio of the number of atoms of the metal element M to the total number of atoms of the nickel element and the metal element M in said region when the nickel particles are measured by ICP emission spectrometry.
