摘要
采用传统的陶瓷工艺,低温烧结制备了Bi2O3-H3BO3-SiO2-ZnO(BBSZ)玻璃掺杂的NiCuZn铁氧体材料,研究了BBSZ掺杂量对铁氧体材料烧结密度、微观形貌和电磁性能的影响。研究表明,适量的BBSZ掺杂可以显著改善铁氧体的烧结性能和微观结构,进而对其电磁性能产生明显的影响。当BBSZ掺杂量为质量分数0.75%时,获得的铁氧体样品均匀致密且具有最佳的综合电磁性能,其烧结密度ρ、起始磁导率μi、品质因数Q以及饱和磁感应强度Bs分别为5.19g/cm3,164,122和403mT,均达到最大值,而其矫顽力Hc则达到最小值217A/m。
Using the traditional ceramic technique,Bi2O3-H3BO3-SiO2-ZnO （BBSZ） glass doped NiCuZn ferrites were prepared through low temperature sintering.The effects of BBSZ content on the sintered density,microstructure and electromagnetic properties of NiCuZn ferrites were investigated.The results show that doping proper amount of BBSZ obviously improves the sintering property,microstructure and hence electromagnetic properties of NiCuZn ferrites.Compared with other samples,the ferrite doped with 0.75% （mass fraction） BBSZ shows a uniform and dense microstructure and superior electromagnetic properties;And,its sintered density,initial permeability,quality factor and saturation magnetic induction reach their peak values of 5.19 g/cm^3,164,122 and 403 mT,respectively,while its coercivity reaches the lowest value of 217 A/m.
