ABSTRACT:
A method of manufacturing a ferromagnetic metal powder characterized by continuously drying a slurry of ferromagnetic metal powder formed by wet reduction, in a non-oxidizing gas atmosphere, and subsequently continuously heat-treating the dried ferromagnetic metal powder in a non-oxidizing gas atmosphere. The continuous method prevents the ferromagnetic metal powder from being exposed to excess oxygen to enhance the magnetic properties of the ferromagnetic metal powder. Also, the production efficiency is enhanced.
