通过在Li-Zn铁氧体材料中掺入H3BO3-Bi2O3-SiO2-ZnO (BBSZ)玻璃相(1~4wt%)，利用氧化物法陶瓷工艺合成Li-Zn铁氧体材料。在900℃烧结获得了符合要求的Li-Zn铁氧体材料。讨论了材料的微观结构以及磁性能，包括饱和磁化强度Ms、矫顽力Hc以及剩磁比Br/Bm。结果表明，BBSZ掺杂能显著降低材料的烧结温度，饱和磁化强度Ms随BBSZ掺入量的增加先增大而后略微减小，矫顽力Hc随BBSZ掺入量的增加先明显减小而后略微增加。当BBSZ掺入量为1.5wt%时，可以获得最佳的综合性能。

Using H3BO3-Bi2O3-SiO2-ZnO (BBSZ) glass as dopant, Li-Zn ferrite was successfully prepared at sintering temperature 900℃. The microstructure and the magnetic properties includingMs,Hc andBr/Bmof Li-Zn ferrite were discussed. The result shows that BBSZ-dopant can reduce the sintering temperature significantly. As the amount of BBSZ increases, the saturation magnetizationMs increases first and then decreases slightly, and the coercivityHcdecreases significantly and then increases slightly. The best property was achieved for 1.5wt% BBSZ-dopant.
