ABSTRACT:
A magnetic metallic powder comprising iron or iron-cobalt as its fundamental component and, besides, molybdenum in an amount of 0.05 to 5% by weight of the fundamental component. The magnetic powder is produced by heat reduction of a molybdenum-doped iron oxide powder which may optionally contain cobalt. The presence of molybdenum suppresses agglomeration of the heated particles and produces an improvement on the coercive force of the metallic powder.
