High-strength nickel-zinc ferrite material and preparation method thereof
The high-strength nickel-zinc ferrite material comprises a main material and an auxiliary material, the main material comprises the following raw materials in percentage by weight: 65 to 66 percent of Fe2O3, 12 to 13 percent of NiO, 15.5 to 16.5 percent of ZnO and 4.5 to 5.5 percent of CuO; the auxiliary materials comprise Bi2O3 and WO3, the weight of the Bi2O3 is 0.1 to 0.2 percent of the weight of the main materials, and the weight of the WO3 is 0.15 to 0.25 percent of the weight of the main materials; by adjusting the ratio of the main materials to the auxiliary materials, grains of the ferrite material are tightly combined to obtain a compact magnet, so that high sintering density is obtained, the core bending strength and the pendulum bending strength of a product are further improved, and the relatively high use requirements on the ferrite material are met.
一种高强度镍锌铁氧体材料，包括主料和辅料，所述主料按重量百分数计，其原料包括：65‑66％Fe2O3、12‑13％NiO、15.5‑16.5％ZnO和4.5‑5.5％CuO；所述辅料包括Bi2O3和WO3，其中，Bi2O3重量为主料重量的0.1‑0.2％，WO3重量为主料重量的0.15‑0.25％；本发明通过调整各主料和辅料的配比，使铁氧体材料的晶粒之间紧密结合，以获得致密的磁体，从而获得高烧结密度，进而提高产品的芯折强度和摆折强度，以满足对铁氧体材料较高的使用要求。
