Description
技术领域
本发明涉及磁铁氧体材料技术领域,尤其涉及一种毫米波LTCF生瓷带制备方法。
背景技术
雷达相控阵体系的小型化、集成化成为当前射频、微波毫米波器件及组件的重要发展方向,传统环行器由于体积较大原因严重制约了雷达阵面的轻薄化。基于低温共烧旋磁铁氧体材料(LTCF)技术可实现环行器的轻薄化、集成化,打破传统阵面架构,使得新型远程毫米波陆基雷达的天线阵面的厚度、重量、体积大幅减少,集成度显著提高。
LTCF技术应用的旋磁材料不是传统成型工艺制备的块体材料,而是流延工艺制备的生瓷带,需要生瓷带与电路的金属浆料匹配共烧,因此,毫米波LTCF生瓷带的要求是:在低于920℃烧结温度下具有高饱和磁化强度、低损耗、低气孔率、高居里温度等特性。
但是,目前的流延工艺制备的生瓷带,在流延浆料的制备过程中,加入了粘结剂、增塑剂、溶剂、分散剂等,导致流延工艺制备的生瓷带电磁性能较成型工艺材料性能差。LTCF设计需要与直接印刷在旋磁生瓷带上的Ag导体共烧,为防止短路,要求生瓷带具有很高的电阻率ρ,而电阻率与介电损耗成反比,高电阻率意味着材料必须有的低介电损耗。
为了解决上述问题,本领域技术人员作了很多努力,比如,中国申请号:CN202110943087.6,一种基于LTCC技术的NiCuZn铁氧体制备方法,公开了:在预烧工艺中二元掺杂Bi2O3和Co2O3,采用成型工艺、烧结温度925℃,得到致密度高,孔隙小,饱和磁化强度到了55.858emu/g(约为3600 Gauss),矫顽力为4.87Oe的NiCuZn铁氧体材料,该专利虽然没有公开介电损耗性能,但是,该专利的材料矫顽力大,从而可以推断材料的电磁损耗大,另外,所掺杂的Co2O3的熔点895℃,虽然比NiO、ZnO等氧化物低,但Co离子是快驰豫离子,Co离子添加会导致材料的线宽,尤其是有效线宽的成倍增加,也会使材料介电损耗增大。
又比如,中国专利申请号:CN202110324931.7,一种高饱和磁化强度低温烧结LiZn铁氧体材料及其制备方法,发明通过Zr离子部分取代的LiZn铁氧体中的Zn离子,得到LiZn铁氧体材料:Li0.43Zn0.27Zr0.13Fe2.17O4,采用成型工艺,925℃烧结时样品密度能够达到4.76g/cm3 ,Bi2O3助烧剂的用量为1.5wt%时,饱和磁化强度高达102.4emu/g、矫顽力为192A/m、铁磁共振线宽为205Oe,该专利是LiZn铁氧体材料,相对于NiZn铁氧体材料而言,损耗更大,另外材料的致密性也较差,因为流延工艺制备的LiZn生瓷带的气孔率一般在3.5%左右,NiZn生瓷带的气孔率一般在2%左右。
又比如,中国专利申请号:CN202011071585.8,一种高饱和低温烧结旋磁Ni系尖晶石铁氧体材料,铁氧体材料化学分子式为Ni(1-a-b-c)ZnaCubCocMndFe2-dO4,在900℃烧结所得的铁氧体材料,饱和磁化强度≧4000Gs,介电损耗正切(tanδ)≦1×10-3,铁磁共振线宽(ΔH)≦150Oe,饱和磁化强度≧4600Gs,介电损耗正切(tanδ)≦1.5×10-3,铁磁共振线宽(ΔH)≦250Oe。该专利具有高饱和磁化强度高,但介电损耗大。
即,对于毫米波应用的高饱和磁化强度的LTCF生瓷带,目前报道最好性能是:饱和磁化强度4πMs≧4600Gs,介电损耗tanδε≦1.5×10-3,铁磁共振线宽ΔH≦250Oe。对于应用来说,损耗还是较大,尤其是介电损耗在10-3级别。

微波铁氧体材料的电磁性能主要包括本征特性及非本征特性,饱和磁化强度4πMs、居里温度TC等是材料的本征参数,只取决于材料各次晶格上磁性阳离子的数量及分布情况,而介电损耗tanδε、铁磁共振线宽ΔH等不仅与其化学成分和晶体结构有关,而且与密度、晶粒尺寸、气孔率以及它们在晶粒内部和晶粒之间的分布关系密切,是材料微结构的结构敏感量,所以,本专利在配方设计中引入低熔点氧化物Bi2O3,在较低温度下形成液相或过渡液相,促进材料的低温烧结致密化,用CuO、Li2CO3、V2O5进行适量离子代换,形成具有较低熔点的改性化合物,促进烧结固相反应进程,达到低烧结温度下固相反应完全的目的;其中,Li1+和V5+联合取代2个Fe3+,Li1+和V5+作为一个整体使用,一是电价平衡,二是离子个数相等,在工艺设计中,各工序采用最佳工艺参数配合,制备致密、均匀的生瓷带,实现生瓷带高饱和磁化强度、低损耗、高温度稳定性的制备。
本发明在生瓷带配方设计中引入低熔点氧化物Bi2O3掺杂,并在适当的时机(二次球磨)中加入,在较低烧结温度下形成液相或过渡液相,促进材料的低温烧结致密化;在实施例2的基础上做对比例,即Bi2O3在预烧工艺加入,其余条件不变,包括相同烧结温度下,ΔH为150 Oe左右,tanδε在5×10-4,可见,二次球磨加入Bi2O3比预烧工艺加入,材料损耗性能更优。
另外,本发明用适当的金属离子进行适量代换,Cu2+取代Ni2+,Li1+和V5+联合取代2个Fe3+的形成具有较低熔点的改性化合物,达到降低烧结温度的目的,使生瓷带在880℃~920℃烧结固相反应完全,具有单一的尖晶石相结构,使生瓷带具有较低的电磁损耗;采用Mn2+配合缺铁量δ组合设计,抑制烧结中Fe2+的产生,从而提高电阻率ρ,即达到降低介电损耗tand e的目的,又可避免与Ag导体共烧短路。工艺设计中,各工序采用最佳工艺参数配合,首先制备电磁性能优异的旋磁粉,料粉料粒度D50控制在1.0μm~1.5μm,烧结生瓷带不易边沿翘曲;旋磁粉料、增塑剂、分散剂、粘结剂、有机载体适当比例配置混合制浆,使流延浆料的黏度为1500mPa·s~3000 mPa·s,流延生瓷带均匀、致密。
与现有技术相比,本发明的优点在于: 本发明制备的尖晶石NiZn毫米波LTCF生瓷带,烧结温度在880℃~920℃范围,可实现与金属浆料(银浆、金浆)共烧。所制得的旋磁生瓷带致密、均匀、单相的尖晶石结构,具有烧结温度低、损耗小、居里温度高、气孔率低等优点,电磁性能优异,饱和磁化强度4πMs在4400Gauss~4600Gauss,铁磁共振线宽△H在185Oe~109Oe,介电损耗tand e均小于5×10-4,气孔率低于1.9%,且具有较高的居里温度373℃,自旋波线宽△Hk大于15Oe,具有一定的功率承受能力。
