提高干压各向异性SrM磁体磁性能的方法

Methods to Increase the Magnetic Properties of Dry-press Anisotropic SrM Ferrite

以Y30H-1的SrM预烧料为原料,通过对二次添加剂、二次球磨及烧结曲线的调整,做出了Br≥380mT,Hcb≥240kA穖-1,Hcj≥250kA穖-1,(BH)max≥27.0kJm-3的干压各向异性锶铁氧体产品。

By using Y30H-1 presintered SrM powder, adjusting the additives, sintering conditions, and controlling the main size of milling powder, dry-press anisotropic ferrite magnets were produced with Br≥380mT, Hcb≥240kA穖-1, Hcj≥250kA穖-1 and (BH)max≥27.5kJ穖-3.
