| 摘 要： | 采用固相反应法制备Ba2Co0.2Zn0.9Cu0.9Fe12O22(Co2Y)铁氧体粉末,通过添加不同量的Bi2O3-H3BO3-SiO2-ZnO(BBSZ)玻璃在不同温度下进行烧结,研究掺杂BBSZ玻璃对Co2Y六角铁氧体材料的烧结行为、显微结构和电磁性能的影响。结果表明,适量的BBSZ玻璃掺杂能得到晶粒均匀、结构致密的Co2Y铁氧体材料,起到良好的低温助烧作用。BBSZ玻璃掺杂为0.8wt%的Co2Y型铁氧体在900℃获得较好的电磁性能及致密性:ρ=5.33g/cm3,μi=9.19,ε=18.13,tanδμ(200MHz)=0.0235,tanδε(200MHz)=0.0018。

| Abstract: | Y-type hexaferrites were prepared by solid state reaction method and were sintered at different temperature with different adding content of Bi2O3-H3BO3-SiO2-ZnO (BBSZ) glass. The effects of BBSZ glass on sintering behavior, microstructure and electromagnetic properties of Y-type hexaferrites were investigated. The result indicates that Y-type hexaferrites with uniform crystal grains, higher density and lower sintering temperature can be obtained when adding proper amount of BBSZ, which promotes sintering at lower temperature. The sample with 0.8wt% of BBSZ glass sintered at 900℃ exhibits such good electromagnetic property and high density as:ρ=5.33g/cm3,μi=9.19,ε=18.13, tanδμ=0.0235, tanδε=0.0018. |
