Abstract

Pure lead hexaferrite (PbFe12O19) was obtained using two different methods of preparation, the solid state reaction and the chemical  coprecipitation.  It  was  found  that  the  lead  hexaferrite  prepared  by  the  solid  state  method  is  obtained  without secondary phases by adding 33.09 % of lead oxide as an excess and sintering at 950 °C during one hour, also the pure lead hexaferrite prepared by the coprecipitation method is obtained at 700 °C without lead losses. We studied the structural and magnetic properties of both samples, a remarkable increase  was  found in the coercivity field of the sample prepared by coprecipitation  as  well  as  a  reduction  of  the  magnetic  saturation,  compared  with  the  sample  prepared  by  the  solid  state reaction.  This  behavior  is  attributed  to  the  morphologic  characteristics  and  the  microstructure  that  is  obtained  in  an inherently way to the preparation method
