Low-cost high-remanence permanent magnetic ferrite and preparation method thereof
The invention discloses a low-cost high-remanence permanent magnetic ferrite and a preparation method thereof. The chemical formula of the permanent magnetic ferrite is La<1-(1+m)x-y>CaSrBaFe<2n-z>Co O<19>, x is 0.02-0.08, y is 0.05-0.5, z is 0.1-0.25, m is 4-5, n is 5-5.7, 2n-z is 10-11.2, mx is 0.1-0.4, and 1-(1+m)x-y is 0.2-0.4. The invention also provides the preparation method of the ferrite. The low-cost high-remanence permanent magnetic ferrite is uniform in grain, excellent in remanence performance and low in production cost; and the preparation method is simple in process, and the cost can be effectively reduced.
