Samarium and cobalt doped strontium ferrite and preparation method thereof
The invention relates to the technical field of permanent magnetic ferrite materials, in particular to strontium ferrite doped with samarium and cobalt and a preparation method thereof, the molecular formula of the strontium ferrite doped with samarium and cobalt is Sr < 1-x > Sm < x > Fe < 12-x > Co < x > O < 19 >, and x is 0, 0.01, 0.02, 0.03, 0.04, 0.05 or 0.1. On the basis of Sr1-xSmxFe12-xCoxO19 ferrite, a solid-phase reaction method is adopted in the preparation process, Fe < 3 + > is replaced with Co < 2 + >, Sm is replaced with Sr to improve the magnetic performance and the electrical performance of the material, the preparation process is simple, the process is free of pollution, and the obtained material has high sintering density, initial permeability and direct-current resistivity and low coercive force and dielectric loss at the same time; key materials can be provided for high-frequency inductors and capacitors, and the current situation that related electronic components in the high-frequency weak current field are lacked in China is solved.
