Ferromagnetic metal powder and process for preparation thereof.

摘要

A ferromagnetic metal powder comprises a ferromagnetic metal particle composed mainly of iron, a silicon compound layer formed on the surface of the ferromagnetic metal particle in such an amount that the amount of silicon is 0.1 to 1% by weight based on iron in the ferromagnetic metal particle, and a layer containing a nonferrous transition metal element compound, which is formed on the silicon compound layer.
