METAL COMPOSITE COMPOUND

Abstract

A metal composite compound includes at least Ni. In a scatter plot obtained by measuring a powder of the metal composite compound using a scanning electron microscope-energy dispersive X-ray spectroscopy, with a horizontal axis representing a projected area circle equivalent diameter (μm) of particles of the metal composite compound and a vertical axis representing an Ni content ratio (mol %) of the particles of the metal composite compound, a slope S of an approximate straight line calculated by a least squares method is more than 0.2. When a particle diameter at which a cumulative volume ratio from a small particle side in a volume-based particle size distribution reaches 10% is defined as D10 (μm), a standard deviation X of the Ni content ratio (mol %) in particles having a projected area circle equivalent diameter of the D10 (μm) or less is 1.6 mol % or more.
