| Abstract: |
| Using the mill scale as the raw materials is the common method for production of permanent magnetic ferrite In the production process,it is common for forming the phenomenon of deposit Sr and the mottle of permanent magnetic ferrite In this paper,forming cause and mechanism of deposit Sr and the mottle of permanent magnetic ferrite is mainly described The effective control process of pre-sintering and secondary addition technology is introduced The difficult point of the mottle and water vestige of the pressed compact and sintered ferrite of permanent magnetic ferrite is solved |
