| Abstract: | Oxide additives with low melting point, such as V_2O_5,Bi_2O_3, and MoO_3, can promote densification and improve the magnetic properties of magnetic head ferrite via liquid phase formation during sintering. In this study,high density MnZn magnetic head ferrite with a nominal composition of Mn_(0.60)Zn_(0.32)Fe_(2.08)O_4 was prepared by liquid-phase sintering process. |
