摘要:
A powder for a powder magnetic core, a powder magnetic core, and methods of producing those products are provided, so that mechanical strength of a powder magnetic core can be enhanced by hydrosilylation reaction between vinylsilane and hydrosilane without degrading magnetic properties. The powder for a powder magnetic core is composed of magnetic particles 2 having a surface 21 coated with an insulating layer 3, wherein the insulating layer 3 includes a polymer resin insulating layer 33 comprising vinylsilane 4 and hydrosilane.
