Description

一种微波介质陶瓷材料及制备方法
技术领域
本发明涉及一种微波介质陶瓷材料及制备方法,属于材料技术领域。
背景技术
在相同的微波谐振频率下,介电常数εr越大,介质谐振器尺寸越小,电磁能量越集中于介质体内,受环境的影响也就越小,但现有材料体系中过高的介电常数往往带来Q×f值的下降。因此,中等介电常数的微波介质材料目前被广泛用于天线等产业化的产品,其具有价格低、工艺简单、性能合适的特点。
中等介电常数的微波介质陶瓷材料,适合商业化生产的主要是以BaTi4O9、Ba2Ti9O20、(Zr、Sn)TiO4、CaTiO3-LnAlO3等为基的微波介质材料。其中(Zr、Sn)TiO4系材料中,ZrO2、SnO2两种原材料的价格高昂。而CaTiO3-LnAlO3系材料烧结温度高达1450℃~1500℃,成本较高,工艺控制难度大。BaTi4O9/Ba2Ti9O20系材料原材料价格低廉,工艺简单,但因其晶粒结构的固有特性,易造成晶粒拔出,陶瓷材料表面爆孔等缺陷。Sea-Fue Wang等发表的《Effects of additives on the microstructure and dielectric properties ofBa2Ti9O20》,可以看到晶粒为长方柱、晶界分明。
BaTi4O9的最佳合成温度是950℃左右,晶胞参数为
Figure BDA0002356410010000011
而Ba2Ti9O20的最佳合成温度在1200℃左右,晶胞参数为
Figure BDA0002356410010000012
从晶胞参数上看,就知道我们需要尽可能的多形成长宽高比小的Ba2Ti9O20,才有利于晶粒紧密堆积。李佶莲等发表的《Ba2Ti9O20基微波介质陶瓷的微观组织与微波介电性能》,其传统固相法制备的陶瓷材料介电性能为:εr=39.53,Q×f=33800GHz,τf=1.68ppm/℃。
发明内容
本发明的目的在于克服现有技术中存在的不足,而提供一种微波介质陶瓷材料及其制备方法。
本发明实施例解决上述问题所采用的技术方案是:一种微波介质陶瓷材料,其特征在于,按重量份配置包括以下组分:
Ba2Ti9O20 80~120份;
Sm2O3 1~25份;
助剂 0.1~3份。
本发明实施例按重量份配置包括以下组分:
Ba2Ti9O20 90~110份;
Sm2O3 1~20份;
助剂 0.1~2份。
本发明实施例所述助剂选自MnO2、Al2O3、Fe2O3或SiO2中的一种或几种。
本发明实施例所述微波介质陶瓷材料的介电常数为40~50。
本发明实施例所述微波介质陶瓷材料的品质因数大于等于10000GHz。
本发明实施例还提供一种微波介质陶瓷材料的制备方法,其特征在于,包括以下步骤:
A、配料:将碳酸钡、二氧化钛、氧化钐及助剂按照设定的组分称重配料;
B、混合:将配料后的原料预混匀后进行球磨处理,球磨介质为锆球与去离子水,然后置于150℃烘箱中经12小时干燥,得到干燥的粉料;
C、预烧:将干燥的粉料置于氧化铝坩埚中,并于1000℃~1150℃碳棒炉中预烧2~4小时,得到原料粉末;
D、造浆:将原料粉末球磨粉碎20~26小时,球磨介质为锆球与去离子水,得到粘稠状的浆料;
E:成型:在浆料中添加5wt%~20wt%粘结剂并喷雾造粒后,再压制成型,最后在1250℃~1350℃碳棒炉中成烧3小时。
本发明实施例所述步骤B中的球磨方式为超细化沙磨处理。
本发明相比现有技术突出且有益的技术效果是:
1、本配方设计中BaSm2Ti4O12第二相的少量引入不需两步合成,通过Sm(钐)掺杂的形式直接通过固相反应一步合成。
2、本配方设计中Sm(钐)为一次性掺杂,少量掺杂的Sm可以生成BaSm2Ti4O12第二相,可以阻碍主晶相的过度生长,缓和填充BaO-TiO2体系晶粒间的缺陷。
3、本工艺配方主相选择为Ba2Ti9O20,相比BaTi4O9更利于瓷块致密化程度提升;混合中引入超细磨,其有利于晶粒生长的均匀性,减小晶粒生长时大小不一而相互挤压造成的局部应力。
4、本发明实施例中的微波介质陶瓷材料的介电常数在40~50范围内可调;品质因数Q×f值良好:≥10000GHz;谐振频率温度系数低,温度稳定性好,制造成本低,采用传统固相合成工艺,可以应用在基带天线、导航天线等领域。
