Title:
FERRITE MAGNETIC MATERIAL AND FERRITE SINTERED MAGNET
Document Type and Number:
WIPO Patent Application WO/2017/065408
Kind Code:
A1
Abstract:
The present invention produces a ferrite magnetic material having a remarkably higher maximum energy product ((BH)max) than a conventional ferrite magnetic material through the induction of a high saturation magnetization and a high anisotropic magnetic field by simultaneously adding Co and Zn to substitute some of Fe and adjusting the content ratio of Zn/Co. In addition, the present invention can produce a desired magnetic material at a lower cost than a conventional CaLaCo-based ferrite magnetic material substituted with only Co by using Zn, which is relatively at least seven times cheaper than Co, together with Co.
