Lanthanum-doped barium ferrite wave-absorbing material and preparation method thereof
The invention belongs to the technical field of preparation of wave-absorbing materials, and relates to a lanthanum-doped barium ferrite wave-absorbing material and a preparation method thereof.The lanthanum-doped barium ferrite wave-absorbing material is obtained by partially substituting Fe < 3 + > in barium ferrite with La < 3 + > by using citric acid as a complexing agent through a sol-gel method; the preparation method is beneficial to adjustment of electromagnetic parameters of the barium ferrite and improvement of dielectric properties, and the saturation magnetization and coercive force of the barium ferrite can be changed and the static magnetic properties of the barium ferrite can be regulated and controlled only by adjusting the doping amount of La < 3 + >.
本发明属于吸波材料制备技术领域，涉及一种镧掺杂钡铁氧体吸波材料及其制备方法，利用溶胶‑凝胶法以柠檬酸为络合剂将钡铁氧体中的Fe3+用La3+部分取代得到镧掺杂的钡铁氧体，通过稀土元素镧掺杂钡铁氧体，有利于调节钡铁氧体的电磁参数，提高介电性能，且只需调节La3+掺杂量就可以改变钡铁氧体饱和磁化强度、矫顽力，调控钡铁氧体的静磁性能。
