用传统陶瓷工艺制备了M型SrFe12-xCrxO19(x=0～0.6)铁氧体，利用X射线衍射、扫描电子显微镜和B-H分析仪对样品的结构与磁性能进行了表征。研究了铬含量、烧结温度和复合添加剂对磁体性能的影响。结果表明，适量的铬取代和复合添加可以提高锶铁氧体的综合磁性能；当 x=0.2时，在相对低的温度（1135～1165℃）烧结，其磁性能达到TDK的FB6H性能水平。其中，最佳磁性能可达到Br=401.7mT、Hcb=300.5kA/m、Hcj=353.1kA/m和(BH)max=31.4kJ/m3。

M-type SrFe12-xCrxO19 (x=0-0.6) ferrite were prepared by conventional ceramic process. The samples were characterized by means of X-ray diffractometer (XRD), scanning electron microscopy (SEM) and B-H hysteresis curve measurements. The influences of chromium content, sintering temperature and compound additives on magnetic properties were investigated. Measurements show that suitable Cr3+doping and using compound additives can improve magnetic properties of the samples. With x=0.2, the magnetic properties have reached the level of TDK FB6H at sintering temperature of 1135 to 1165℃, in which optimal properties reach the value of Br=401.7mT, Hcb=300.5kA/m, Hcj=353.1kA/m and (BH)max=31.4 kJ/m3.
