| abstract |
The invention provides a ferrite material, which comprises main powder and an additive; the main powder body includes: fe in mole percent based on the main powder 2 O 3 : 45-49.2 mol%, ZnO: 10-35 mol%, CuO: 8-14 mol% and the balance of NiO; the additive comprises: based on the weight of the main powder, V 2 O 5 ：0～0.2wt％、Co 2 O 3 : 0 to 1 wt%. The invention also provides a preparation method of the ferrite material. The ferrite material of the invention does not contain Bi, has high purity, good sintering performance and uniform structure, and can be used for manufacturing inductance devices with high compactness, high strength and high reliability. The preparation method of the ferrite material of the invention makes it possible to manufacture the inductance device with high compactness, high strength and high reliability. |
