摘　　要：以炼钢烟尘为原料制作永磁钡铁氧体，通过掺杂改善制备中的固相反应；通过控制气氛与温度控制物料间的相反应；通过对原料的活化和晶型转化使形成永磁钡铁氧体所需要的晶型．采用Ｘ射线分析、电子衍射和显微形貌分析等方法，阐述了永磁钡铁氧体在制备过程中各种因素的作用和相互影响．With the furnace dust produced in steel making as raw material hard barium ferrites are made.The required crystal phase of these ferrites is obtained through the following process:doping,control of air and temperature,activation of the raw material,and the crystal phase transformation.The action and interaction of different factors in the preparation of the ferrites are explained by methods such as X ray analysis.electron diffraction,and microphotography.
