Ferrite magnet with salt and manufacturing method of the same

摘要

There is provided a ferrite magnet with salt including 40 to 99.9 weight % of ferrite and 0.1 to 60 weight % of salt, wherein the salt has a melting point lower than a synthetic temperature of the ferrite, and the salt is melt to form a matrix between the ferrite particles, and a manufacturing thereof. In addition, there is provided a ferrite magnet with salt, having advantages in terms of process conditions due to fast synthesis reaction at low temperatures compared to typical magnets, easily obtaining nano-sized particles having high crystallinity, preventing cohesion between particles and particle growth by molten salt, allowing sintering at temperatures lower than typical during the molding and sintering processes for producing a ferrite magnet with salt due to synthesized ferrite magnetic powder with salt thus preventing the deterioration of magnetic characteristics due to particle growth, and allowing alignment in the direction of magnetization easy axis to obtain higher magnetic characteristics.
