| 摘 要： | 采用传统固相反应法制备了Y1.05Bi0.75Ca1.2Fe4.4-xV0.6BxO12（Bx：Bi—CVG）系列铁氧体试样。借助XRD、SEM及MATS等技术手段研究了烧结助剂B20，对Bi—CVG铁氧体的体积密度、相组成、微观结构及磁性能的影响。研究结果表明，掺B可以有效降低Bi—CVG铁氧体的烧成温度，提高材料的烧结密度并且影响其微观结构和磁性能。在1040℃×6h条件下烧结、B掺杂量为x=0．025时，制备出综合性能良好的Bi—CVG铁氧体材料：室温时D=5．11g／cm^3，DR.T=97．2％，Bs=37．30mT，Br=25．54mT，Hc=0．87kA／m。

| Abstract: | Bx:Bi-CVG ferrite samples were prepared by solid-state reaction.The effect of sintering additives of B2O3 on the bulk density,phase structure,microstructures and magnetic properties of Bi-CVG were investigated by means of XRD,SEM and MATS.The results showed that doping B can lower sintering temperature of Bi-CVG samples.B doping leads to an increase in density and has an influence on microstructures and magnetic properties of samples.With B dopant dose x=0.025 and as sintered at 1040℃ for 6h,the sample obtained has good integrated properties:with D=5.11g/cm3,DR.T=97.2%,Bs=37.30mT,Br=25.54mT,Hc=0.87kA/m in room temperature. |
