| 摘要 |
A method for producing ferrite hollow particles having a hollow structure formed by mutual sintering of ferrite powder, including: a) a step of mixing a resin powder and a ferrite powder of a particle size smaller than that of the resin powder under an under compaction thereby forming ferrite powder-coated particles in which ferrite powder coats, in a partially embedded state, surface of the resin powder; and b) a step of heat treating the obtained ferrite powder-coated particles thereby removing the resin powder and mutually sintering the ferrite powder.
