| 摘 要： | 讨论了溶胶-凝胶法制备钡铁氧体材料的过程中,主要工艺参数,即烧结温度、烧结时间、Fe/Ba比率对产物组成及磁性能的影响.研究结果表明,增加烧结时间和烧结温度有利于提高产物的饱和磁化强度(Ms),但对矫顽力(Hci)的影响甚微;Fe/Ba比率的变化主要影响产物组成中主相BaFe12O19和杂质相BaFe2O4的比率,进而影响产物的磁性能.

| Abstract: | Influence of stoichiometry and heat treatment conditions on the magnetic properties and phase constitution of Ba-ferrite powder prepared by sol-gel route are investigated.The results show that increasing time and temperature is beneficial to saturation magnetization(M_s),whereas the coercivity(H_(ci))is only slightly affected.The variation of the Fe/Ba ratio leads to the formation of different proportions of BaFe_(12)O_(19) and BaFe_2O_4,which directly af- fects the magnetic properties. |
