摘　　要：采用BPb玻璃为助烧剂,870℃烧结Y型平面六角结构软磁铁氧体,分析其烧结工艺、显微结构及起始磁导率和介电常数的频率特性。研究发现,含Co、Zn、Cu的Y型铁氧体材料(Ba_2Me_2Fe_(12)O_(22),Me=Co、Zn、Cu)在甚高频段具有良好的磁性能,采用BPb玻璃为助烧剂可有效地实现此种材料的低温烧结,并大大改善其介电性能。The sintering process, microstructure,dispersion character of initial permeability and dielectric constant of the low-temperature sintered Y-type hexagonal ferrites doped with BPb glass are reported.Experimental results show that complex Y -type hexaferrite containing Co, Zn and Cu(Ba2Me2Fe12O22, Me = Co,Zn, Cu) shows excellent magnetic properties in very high frequency. The addition of BPb glass can lower the sintering temperature effectively and improved the dielectric property at the same time.
