发明名称 MANUFACTURE OF HEXAGONAL CRYSTAL SYSTEM FERRITE
摘要 PURPOSE: To provide a manufacturing method of a ferrite having high Br characteristics by performing a sintering operation or a hot hydrostatic sintering operation in an atmosphere containing a very small amount of oxygen. CONSTITUTION: The hexagonal crystal system ferrite manufacturing method is the method in which the magnetic anisotropy molded body of hexagonal ferrite fine powder raw material, having average grain size of 0.5μm or smaller and containing a kind of metal selected at least from Ba, Sr, Ca and Pb, and Fe are used as a constituent element, and it is sintered in an atmosphere wherein the quantity of oxygen is controlled.
