More Information
Summary:Provided is an iron-based soft magnetic powder for dust cores that enables production of a dust core having high density and low iron loss. An iron-based soft magnetic powder for dust cores comprises: an iron-based soft magnetic powder; a condensed aluminum phosphate layer on particle surfaces of the iron-based soft magnetic powder; and a silicone resin layer on a surface of the condensed aluminum phosphate layer, wherein the condensed aluminum phosphate layer is a continuous coating, and a total mass of the condensed aluminum phosphate layer and the silicone resin layer is 0.60 mass % or less with respect to 100 mass % of a total mass of the iron-based soft magnetic powder, the condensed aluminum phosphate layer, and the silicone resin layer.
