Lanthanum-cobalt permanent magnetic ferrite and preparation method thereof
The invention belongs to the technical field of permanent magnetic materials, and discloses lanthanum-cobalt permanent magnetic ferrite and a preparation method thereof. The lanthanum-cobalt permanent magnetic ferrite comprises a ferrite main phase with a molecular formula of Sr<1-x-y>CaLaFe<2n-z>Co O<19>, x, y and z represent the adding molar quantity of main metal elements, the value range of x is 0.17-0.3, the value range of y is 0.348-0.42, the value range of z is 0.29-0.35, and the value range of n is 5.1-5.4. The lanthanum-cobalt permanent magnetic ferrite further comprises an adding phase and a dispersing agent, wherein the adding phase is a compound containing at least one element of B, Si or Ca. According to the lanthanum-cobalt permanent magnetic ferrite disclosed by the invention, the prepared lanthanum-cobalt permanent magnetic ferrite achieves more excellent comprehensive magnetic performance by adjusting the dosage of a formula and a preparation process.
