Abstract
A method for manufacturing a coated metal powder includes: preparing a silanol solution in which a silicon-containing substance is dissolved in an alkaline aqueous solution; charging a metal powder into the silanol solution to obtain a dispersion; and forming a coating containing a silicon oxide on a particle surface of the metal powder by adding an acidic aqueous solution to the dispersion.

A method for manufacturing a coated metal powder, comprising:
- preparing a silanol solution in which a silicon-containing substance is dissolved in an alkaline aqueous solution;
- charging a metal powder into the silanol solution to obtain a dispersion;
- and
- forming a coating containing a silicon oxide on a particle surface of the metal powder by adding an acidic aqueous solution to the dispersion,
- wherein a pH of the dispersion before adding the acidic aqueous solution is higher than the pH of the dispersion after adding the acidic aqueous solution by 0.5 or more and 4.0 or less.
