【摘要】 采用陶瓷工艺制备了Al替代的Ni0.5Zn0.5AlxFe2-xO4(x=0~0.10)铁氧体材料,用XRD、B-H分析仪和阻抗分析仪对其结构和磁性能进行了研究。实验发现,最佳烧结温度为1 250℃,过高和过低的烧结温度不利于降低磁芯损耗。当Al3+替代量x=0.06时,铁氧体能获得较好综合磁性能。更多还原

【Abstract】 Al substituted Ni0. 5Zn0. 5AlxFe2-xO4( x=0-0.10) ferrite materials were prepared by using ceramic technology,XRD,B-H analyzer and impedance analyzer were applied to investigate its structural morphological and magnetic properties. The experimental results indicate that the best sintering temperature was 1 250 ℃ and an over-high or over-low sintering temperature was adverse to reduce the magnetic core loss. Ferrite can achieve a preferably integrated performance with x = 0. 06.更多还原
