摘　　要：以完成预烧的常规生产配方的钇铁石榴石铁氧体废料为主体原料,加入一定比例的新料,调整Y^(3+)、Fe^(3+)、Ca^(2+)、Sn^(4+)比例重新制备铁氧体材料,并对其结构和磁性能进行表征。结果表明,样品均为单一的立方相石榴石结构,气孔状态有了明显的改善;同时铁磁共振线宽ΔΗ从65 Oe降至12.5 Oe,介电损耗角正切tanδ保持在1×10^(-5)以下。这为工业生产中铁磁共振线宽异常的石榴石型微波铁氧体材料提供了一种通过配方设计进行回收利用的有效途径。New ferrites were prepared by using ferrite waste as main material and structure and magnetic properties were characterized.The ferrite waste is conventional yttrium iron garnet which was after prefired,and appropriate amount of new materails were added into it to adjust the ratio of Y^(3+)、Fe^(3+)、Ca^(2+)、Sn^(4+).The results demonstrate that the samples had a single cubic garnet structure,and the pore state was obviously better.Meanwhile,the ferromagnetic resonance linewidth(ΔΗ) decreased from 65 Oe to 12.5 Oe,and the tangent of dielectric loss angle(tanδ) remained below 1×10^(-5).This work provides an effective way,which is formula design to recycle microwave garnet ferrite materials with abnormal ferromagnetic resonance linewidth in industrial production.
