<p>PROBLEM TO BE SOLVED: To provide ferrite particles for functional powder transportation that have handleability indirectly improved using the magnetic properties and physical properties of the ferrite particles by mixing the ferrite particles as a medium with a functional powder.SOLUTION: Ferrite particles for functional powder transportation having a ferrite composition represented by following formula (1) and having an average particle diameter of 200-3,000μm, resin-coated ferrite particles obtained by coating the surface of the ferrite particles with a resin, and a mixture of the ferrite particles or the resin-coated ferrite particles with a functional powder are used.</p> |
