Description

一种功率型镍锌铁氧体材料及其制备方法
技术领域
本发明涉及软磁铁氧体技术领域，尤其是涉及一种功率型镍锌铁氧体材料及其制备方法。
背景技术
功率铁氧体是一种高饱和磁感应强度和磁导率、低功耗材料。在外加高磁场强度、高频的情况下仍然能够保持很低的功率损耗，并且功耗会维持在一个固定值附近，不会随温度的提升而急剧增大，从而使磁心处于一种良性循环。
相比较于MnZn功率铁氧体，NiZn铁氧体具有高电阻率、使用频率高等特点，在很多领域有着广泛的应用，比如工业、农业、军品和民品，并且还能大规模量产，特别适合制作成各种表面贴装用的电磁元器件和表面安装的功率电感器，这为传输较大功率的DC-DC电源模块的小型化和轻薄化奠定了一定的理论基础和应用前景。所以说NiZn功率铁氧体是当代电子设备的不可或缺的重要组成部分。
目前NiZn功率铁氧体材料存在的主要问题有以下几个方面：
(1)材料磁导率升高引起饱和磁感应强度显著下降，居里温度较低，满足不了大电流和高密度安装的应用场合需求；
(2)若将饱和磁感应强度提高，则材料的磁导率又偏低，满足不了电子设备小型化的要求；
(3)耐热冲击、机械强度等仍然较弱，焊接温度较高，如何提高器件耐热冲击性能和铁氧体的强度成为了主要的技术难题。
发明内容
本发明是为了解决现有技术的NiZn功率铁氧体材料所存在的上述技术问题，提供了一种
为了实现上述目的，本发明采用以下技术方案：

一种功率型镍锌铁氧体材料制备方法，包括以下步骤：
(1)将主料和辅料按配比称量后混合均匀，得混合料。
(2)将混合料在氧化性气氛中进行预烧。
(3)将预烧后的混合料砂磨至所需粒径。
(4)在砂磨后的混合料中添加适量粘合剂进行造粒、成型，得生坯。
(5)将生坯在氧化性气氛中烧结成型即得功率型镍锌铁氧体材料。
作为优选，步骤(2)中，氧化性气氛为空气气氛，预烧温度为800～1050℃，保温时间1～6h。
作为优选，步骤(4)中，造粒采用喷雾造粒或机械造粒料。
作为优选，步骤(5)中，烧结温度为950～1200℃，保温时间为2～6h。
因此，本发明具有如下有益效果：
