PROCESS FOR PRODUCING METALLURGICAL POWDER, PROCESS FOR PRODUCING POWDER MAGNETIC CORE, POWDER MAGNETIC CORE, AND COIL COMPONENT

摘要

Disclosed is a process for producing a metallurgical powder, which comprises the steps of: coating the surfaces of a plurality of first particles (10) with a first binder (30); and coating the surface of the first binder (30) with a plurality of second particles (20) having smaller particle sizes than those of the first particles (10). In the step of coating with the second particles (20), the particle diameter of each of the plurality of second particles (20) to be used is one-fifth of the particle diameter of each of the first particles (10) or smaller.
