<p>A magnet manufacturing method in which a calcinated hexagonal-system Ba ferrite is pulverized, formed in a magnetic field, and sintered. The ferrite contains Si components such as SiO2 and Sr components such as SrCO3, and consequently the structure of the sintered body has a main phase of Ba ferrite and contains Sr and Si as intercrystalline components. The anisotropy of shrinkage factor is low, deformation during sintering is small, grinding after sintering can be simplified or omitted, and the density after sintering is high. The coercive force of the magnet is much improved.</p> |
