Abstract
A method for producing a metal powder that includes a first step of uniformly arranging a metal compound on a metal particle, and a second step of converting the metal compound uniformly arranged on the metal particle into a complex metal compound. In the first step, a solution that contains at least one metal element and at least one group 4 element different from the metal element is prepared, the solution being adjusted to have a pH of 5 or less. The prepared solution is mixed with a reductant solution to coprecipitate the metal and the metal compound, thereby producing a slurry that contains a metal powder containing the metal combined with the metal compound. In the second step, a solution or a powder containing at least one second metal element is added to the slurry to convert the metal compound into the complex metal compound.
