MAGNETIC CORE POWDER, POWDER MAGNETIC CORE, AND METHOD FOR PRODUCING MAGNETIC CORE POWDER AND POWDER MAGNETIC CORE

摘要

Provided is a powder (1) for a magnetic core, including: a soft magnetic metal powder (2) ; an insulating coating (3) for covering a surface of the soft magnetic metal powder (2) ; and a lubricating coating (4) for covering a surface of the insulating coating (3). The lubricating coating (4) is formed by eliminating a solvent component and causing a lubricating component to adhere to a coated powder (1') in a lubricant solution (26) supplied into a container (21) in which the coated powder (1') is being stirred in a floating state, the coated powder being formed by covering the surface of the soft magnetic metal powder (2) with the insulating coating (3) .
