Description

一种高频低频兼容的锰锌功率材料及其制备方法和应用
技术领域
本发明涉及电子材料技术领域，更具体地，涉及一种高频磁芯材料及其制备方法和应用。
背景技术
电子材料是现代电子工业和科学技术发展的物质基础，主要是一类应用于电子技术和微电子技术中的材料，包括介电材料、半导体材料、压电与铁电材料、导电金属及其合金材料、磁性材料、光电子材料以及其他相关材料，作为电子材料之一的铁氧体磁芯材料，广泛应用于通信设备和汽车电子等领域。软磁材料在工业中的应用始于十九世纪末，应用范围极其广泛。软磁材料不仅应用于家电领域、信息化领域、汽车领域和 其他配套领域，更是电子元器件生产的主要原材料。而随着电子行业的发展与应用领域的扩展，对磁性材料的要求也越来越高，且对材料特性的分类要求更加细化和专业化，而目前用于变压器U型件的磁芯材料的的稳定性和功耗水平都亟待提高。且当前通信设备和汽车等户外设施在工作过程中都需要经历高温和低温的环境，要保证这些设备能够正常使用，就必须要求使用的磁芯材料从低温-20℃到100℃都具有很高的磁导率。现行技术中的很多铁氧体磁芯材料虽具有较高的起始磁导率，但磁导率的宽温特性很一般，较难在各种环境温度下仍能保持高的磁导率；有些产品虽能实现较好的磁导率宽温特性，但制备成本过高，制备工艺繁琐，不易操作，且现有的铁氧体磁芯材料一般不具有很好的高频低频兼容性，难以实现在不同的使用频率下均具有很低的功耗水平。现有技术CN107352993A公开了一种高频猛锌软磁铁氧体材料及其制备方法，该材料的主要成分虽然也包括铁、猛和锌，但是其主要针对的是锰锌铁氧体高直流叠加性能的提升，对于其频率适用范围的拓宽并未有相关的改善，不具备高低频兼容性。
因此，本发明提供一种高频低频兼容的磁芯材料，适用于100KHZ~500KHZ的高低频环境，对于改善磁芯的适用性能具有非常重要的意义。
发明内容
本发明要解决的技术问题是克服现有功率材料不具有高低频兼容的缺陷和不足，提供一种高频低频兼容的锰锌功率材料。通过特定的含量和组成配伍的主成分和副成分搭配达到很好的综合使用性能的提升，使得锰锌功率材料在100KHz~500KHz条件下都具有很低的功耗水平，具有高低频兼容性。
本发明的目的是提供一种高频低频兼容的锰锌功率材料的制备方法。
本发明的再一目的在于提供一种高频低频兼容的锰锌功率材料在通讯基站、服务器、汽车电子系统中的应用。
本发明上述目的通过以下技术方案实现：
一种高频低频兼容的锰锌功率材料，其原料包括主成分和副成分，其中主成分包括如下摩尔百分比的组分：Fe2O3 52～54％、MnO 38~40％、ZnO 6.0～8.5％，所述副成分组分的质量百分比为：Ca2CO3 0.01~0.02%，V2O5 0.01~0.06 %，Nb2O5 0.01~0.05%，SnO2 0.01~0.06%，Co2O3 0.1~0.3%，TiO20.02~0.3%，ZrO20.01~0.05 %，其副成分的质量百分比是相对于主成分总质量的百分比。
本发明的锰锌功率材料具有高频低频兼容性，在100KHz和500KHz条件下的主要功耗指标均能满足要求，在300KHz左右时仍具有较低的功耗水平和较高的饱和磁通密度。本发明的锰锌功率材料的初始磁导率为3000±25%，在H=1194A/m的条件下测定的饱和磁通密度Bs为530mT左右（25℃），420mT左右（100℃），剩磁Br85mT左右（25℃），70mT左右（100℃），矫顽力Hc10A/m（25℃），7A/m（25℃），居里温度Tc>220℃，电阻率ρ8(Ω.m)。
优选地，其中主成分包括如下摩尔百分比的组分：Fe2O354％、MnO40％、ZnO 6％。
优选地，所述锰锌功率材料的密度为4.75~4.85g/cm3。密度对于锰锌功率材料的功耗的影响为：密度高，晶粒尺寸偏大，高频下的涡流损耗增加，总损耗增加，密度低，晶粒尺寸小，低频下的磁滞损耗增加，总损耗增加，通过控制合适的密度，控制粒径大小及均匀性，调整涡流损耗与磁滞损耗比例，降低宽频下的总损耗。密度高于4.85g/cm3则在500KHz条件下功耗略高，密度小于4.75g/cm3时则在100KHz功耗偏高。
优选地，所述锰锌功率材料的密度为4.78g/cm3。
一种高频低频兼容的锰锌功率材的制备方法，包括如下步骤：
S1. 预烧结：将锰锌功率材料的主成分和副成分混合进行预烧结，预烧结温度为820~850℃；
S2. 制粉：将上述S1预烧结材料加工成粒径大小为0.9~1.0μm的粉料；
S3. 烧结：将上述S2中的粉料烧结得到锰锌功率材料，烧结温度为1280~1300℃。
其中，控制预烧温度为了提高预烧粉料的活性，预烧温度高，粉料预反应成分，烧结时的活性降低，固相反应完全需要更高的烧结温度，在本发明的预烧温度下粉料部分与反应，烧结时粉料活性高，固相反应需要比较低的烧结温度即可可进行完全的固相反应。
优选地，S1中所述预烧结升温速率为1.5~2℃/min。
优选地，S3中所述预烧结升温速率为1.0~2.0℃/min。例如可以为1.0℃/min1.67℃/min，或2.0℃/min。
一种高频低频兼容的锰锌功率材料在通讯基站、服务器、汽车电子系统中的应用也在本发明的保护范围之内。
优选地，所述锰锌功率材料的应用频率范围为100KHZ~500KHZ。
与现有技术相比，本发明的有益效果是：
本发明提供了一种高频低频兼容的锰锌功率材料，通过特定的组分及其含量配伍设置得到一种可以在100KHz~500KHz条件下兼容的锰锌功率材料，功耗指标具有较好的频率特性，且常温饱和磁通密度可以达到530mT左右，高温100℃的饱和磁通密度为420mT。本发明的高频低频兼容的锰锌功率材料的制备过程中通过控制粉剂加工粒径和烧结温度，实现了低功耗和高饱和磁通密度的性能控制，制备达到的高低频兼容材料可广泛应用于通讯基站、服务器、汽车电子系统等领域。
