Wide-temperature-range high-Bs manganese-zinc ferrite magnetic material and preparation method thereof
The invention belongs to the technical field of manganese-zinc ferrite magnetic materials, and particularly relates to a wide-temperature-range high-Bs manganese-zinc ferrite magnetic material and a preparation method thereof. The material comprises a main material component and an additive component, the main material component comprises the following components in percentage by mass: 62-70% of Fe2O3, 25-30% of MnO and 3-7% of ZnO, and the additive component comprises the following components in percentage by mass: 0.03-0.07% of SnO2, 0.30-0.40% of Co2O3, 0.08-0.15% of TiO2, 0.02-0.04% of Nb2O5, 0.20-0.35% of NiO and 0.02-0.05% of V2O5. The manganese-zinc-iron sample material is obtained through primary sanding, primary spray granulation, presintering, secondary sanding, secondary spray granulation, profiling and sintering, meanwhile, the wide temperature range and the high Bs property of the material are guaranteed, and the comprehensive performance of the material is improved.
本发明属于锰锌铁氧体磁性材料技术领域，具体涉及一种宽温高Bs锰锌铁氧体磁性材料及其制备方法。该材料包括主料组分和添加组分，主料组分包括下述质量百分比的成分：62‑70％Fe2O3、25‑30％MnO、3‑7％ZnO，添加组分的各成分按主料组分总质量的百分数计，包括：0.03‑0.07％SnO2、0.30‑0.40％Co2O3、0.08‑0.15％TiO2、0.02‑0.04％Nb2O5、0.20‑0.35％NiO、0.02‑0.05％V2O5。本发明通过一次砂磨、一次喷雾造粒、预烧、二次砂磨、二次喷雾造粒、压型和烧结后得到锰锌铁样体材料，同时保证了材料的宽温性和高Bs性，并改善了材料的综合性能。
