To produce compound powder capable of forming a compacted magnetic core improved in magnetic properties by using amorphous soft magnetic alloy powder and to provide a compacting method therefor.
This compound powder is the one in which, on the surface of powder composed of an amorphous alloy, glass for a binder having a softening point lower than the crystallization starting temp. of the amorphous alloy and an insulating material having fluidity smaller than that of the glass for a binder in the temp. range between the softening point of the glass for a binder and the crystallization starting temp. are formed. In this way, a compacted body having high density and high strength is obtd. without deteriorating the amorphousness of the amorphous alloy powder, and, furthermore, the intergranular insulation of each amorphous alloy powder is secured by the glass for intergranular insulation, so that it is formed as a compacted magnetic core or the like small in eddy current loss and excellent in high frequency magnetic properties.
