Soft magnetic ferrite material with high saturation flux density and preparation method thereof
The invention discloses a soft magnetic ferrite material with a high saturation magnetic flux density, and particularly relates to the technical field of soft magnetic ferrite materials. The high saturation magnetic flux density soft magnetic ferrite material comprises a main material component and an auxiliary material component, the main material component comprises ferric oxide, manganese oxide, zinc oxide and the balance of lithium carbonate by mole percentage; and the auxiliary materials comprise calcium carbonate, molybdenum trioxide, bismuth trioxide, titanium dioxide, zirconium dioxide, rare earth oxide and sodium bismuth titanate. By adding the rare earth oxide, the uniformity of the internal structure of the soft magnetic ferrite material can be improved, the saturation magneticflux density of the soft magnetic ferrite material can be improved, the coercive force and magnetic loss of the soft magnetic ferrite material can be reduced, and the Curie temperature of the zinc-manganese soft magnetic ferrite material can be effectively increased by sodium bismuth titanate. Therefore, the manganese soft magnetic ferrite material still keeps stable dielectric properties in a high-temperature environment.
本发明公开了一种高饱和磁通密度软磁铁氧体材料，具体涉及软磁铁氧体材料技术领域，包括主料成份和辅料成份，所述主成分按摩尔百分比包括三氧化二铁、氧化锰、氧化锌，其余为碳酸锂；所述辅料成份包括碳酸钙、三氧化钼、三氧化二铋、二氧化钛、二氧化锆、稀土氧化物和钛酸铋钠。本发明通过添加稀土氧化物能够改善软磁铁氧体材料内部组织的均匀性，能够提高软磁铁氧体材料的饱和磁通密度，降低软磁铁氧体材料的矫顽力和磁损耗，而钛酸铋钠能够有效提高锌锰软磁铁氧体材料的居里温度，使得锰软磁铁氧体材料在高温环境下依然保持稳定的介电性能。
