Manganese-zinc power ferrite material and preparation method thereof
The invention provides a manganese-zinc power ferrite material and a preparation method thereof. The ferrite material comprises the following main components: 73-74 wt% of ferric oxide, 3-4 wt% of zinc oxide and the balance of manganese oxide, and comprises the following auxiliary components: 500-1000 ppm of calcium carbonate, 200-500 ppm of silicon dioxide, 2000-5000 ppm of cobaltosic oxide, 100-200 ppm of zirconium oxide, 200-600 ppm of niobium pentoxide, 100-200 ppm of zirconium oxide, 200-1000 ppm of titanium dioxide and 1000-2000 ppm of copper calcium titanate. The high-frequency loss of the manganese-zinc power ferrite material is reduced through trace additives such as copper calcium titanate, the power loss of the manganese-zinc ferrite material is greatly reduced while the magnetic conductivity and saturation flux density performance are kept not deteriorated, and the manganese-zinc power ferrite material has high saturation flux density.
本发明提供了一种锰锌功率铁氧体材料及其制备方法，该铁氧体材料的主成分包括73‑74wt％氧化铁、3‑4wt％氧化锌和余量氧化锰，副成分包括500‑1000ppm碳酸钙、200‑500ppm二氧化硅、2000‑5000ppm四氧化三钴、100‑200ppm氧化锆、200‑600ppm五氧化二铌、100‑200ppm氧化锆、200‑1000ppm二氧化钛和1000‑2000ppm钛酸铜钙；本发明通过钛酸铜钙等微量添加剂降低锰锌功率铁氧体材料的高频损耗，在保持磁导率和饱和磁感应强度性能不恶化的同时大幅度降低锰锌铁氧体材料的功率损耗，并且具有高的饱和磁感应强度。
