Description
技术领域
本发明属于功能陶瓷材料领域,尤其是涉及一种具有超高压电响应的无铅压电陶瓷材料及制备方法。
背景技术
压电陶瓷是一种能够将机械能和电能相互转换的信息功能材料。压电陶瓷在机械应力的作用下,引起内部正负电荷中心相对位移而发生极化,导致材料两端表面出现符号相反的束缚电荷即正压电效应。另外,压电陶瓷的自发极化也可以在外电场下发生改变,压电陶瓷极化强度的改变会导致压电陶瓷的伸长或收缩。这种由于电效应转变为机械效应的现象叫做逆压电效应。压电陶瓷所具有的正、逆压电效应使其在日常生活和高新技术领域都有广泛的应用。可以毫不夸张地说,压电陶瓷材料的应用已遍及人们日常生活中的每个角落,如压电点火器、煤气灶、电子钟表、报警器、儿童玩具、蜂鸣器等。此外,银行、商店、安全保密场所的管理以及侦察、破案等场合都可能要用上能验证每个人笔迹和声音特征的压电传感器;医院检查人体内脏器官用的超声仪都要用到压电陶瓷探头;原子力显微镜及其他需要精密定位的设备也都需要压电陶瓷的微位移功能。随着人们对环境保护意识的增强及对以压电材料为基础的功能器件的性能的要求的日趋苛刻,研发高性能无铅压电陶瓷来替代以锆钛酸铅(PZT)为代表的铅基压电陶瓷材料成为一项紧迫而具有经济价值的课题。
目前,对于无铅压电材料的研究主要集中在钛酸铋钠(BNT),铌酸钾钠(KNN),锆钛酸钡钙(BCZT)等体系。经过长时间的研究,这些无铅压电陶瓷材料在制备和性能上都取得了一定的进展,但总体来说每种材料体系都有其明显的缺点,现在还没有一种无铅压电材料能完全取代铅基材料。2004年,Saito等人利用织构化工艺得到了晶粒取向生长的铌酸钾钠基无铅压电陶瓷,其压电系数d33高达416pC/N,逆压电系数高达750pC/N,这些参数都可以和PZT基压电陶瓷相媲美。此研究结果大大地激发了科研工作者研究铌酸钾钠基压电材料及织构化制备工艺的热情。由于铌酸钾钠基无铅压电陶瓷优异的压电性能以及较高的居里温度,也使得铌酸钾钠基无铅压电陶瓷被认为是最具有希望取代铅基压电陶瓷的体系之一。目前对于铌酸钾钠基压电陶瓷材料的研究主要集中在利用元素掺杂来设计多晶型相界以提高材料的压电性能。虽然利用元素掺杂的手段在某种程度上已经提高了压电陶瓷的压电性能,但其居里温度通常也随着掺杂元素的含量的增加而剧烈降低,从而影响了压电陶瓷的温度稳定性。另外,利用元素掺杂的手段,随着掺杂元素的含量的变化陶瓷的成瓷温度也明显不同,从而给陶瓷的烧结带了很大的困难。
材料的性能和结构是密切相关的,通过微观结构的调控,材料的性能通常表现出大幅度的提升。最近,学者Deng等利用TSSG技术生长出了不同取向的KNN单晶发现(100)取向的单晶具有最高的压电系数和机电耦合系数。(Deng H,Zhao X,Zhang H,etal.Orientation dependence of electrical properties of large-sized sodiumpotassium niobate lead-free single crystals.CrystEngComm,2014,16(13):2760-2765.)学者Yang等利用SFSSCG技术生长出了(100)取向的(K0.45Na0.55)0.96Li0.04NbO3单晶,其压电系数高达689pC/N。(Yang J,Zhang F,Yang Q,et al.Large piezoelectricproperties in KNN-based lead-free single crystals grown by a seed-free solid-state crystal growth method.Applied Physics Letters,2016,108(18):182904.)这些结果说明铌酸钾钠基材料经过取向后在某一个方向上性能会有大幅度的提升,然而高质量的单晶一般制备较难、周期较长、成本较高及加工切割比较复杂等显著的缺点,限制了其实用化的发展。
中国专利CN 101863661B公开了织构化铌酸钾钠基无铅压电陶瓷的制备方法,属于无铅压电陶瓷制备领域。采用片状NaNbO3或片状KNbO3为模板或无模板,选用Na2CO3、K2CO3、Li2CO3、Nb2O5、Ta2O5、Sb2O3粉料,按化学式[(KmNa1-m)1-xLix](Nb1-y-zTaySbz)O33制备粉料并获得浆料,经丝网印刷所得到的陶瓷厚膜经过多层层叠压制获得素坯,对素坯排塑后,再进行烧结。该专利与本申请之间的区别主要在于材料组分、制备手段和最终性能的差异。具体来说,该专利使用的材料组分为[(KmNa1-m)1-xLix](Nb1-y-zTaySbz)O3,本申请使用的材料组分为(0.99-x)(K0.5Na0.5)(Nb0.965Sb0.035)-0.01CaZrO3-x(Bi0.5K0.5)HfO3。在制备生坯的过程中该专利使用的是丝网印刷的方法,本申请使用的是流延的方法,利用此方法可以严格控制刮刀的高度使模板在单层膜中能水平排列,从而可以获得更高的织构度。另外,在生坯烧结成瓷过程中该专利使用的是传统烧结法,本申请使用的是优化的两步烧结法,此方法和传统烧结法相比在烧结过程中具有更高的驱动力从而可以获得更高的织构度。本申请和该专利相比获得了更高的晶体取向度(织构度)和压电性能。
发明内容
本发明的目的就是为了克服上述现有技术存在的缺陷而提供一种新组成的无铅压电(0.99-x)KNNS-0.01CZ-xBKH陶瓷材料及该无铅压电陶瓷材料织构化的制备方法。本发明制备的无铅压电陶瓷,采用高长径比的片状铌酸钠为模板,运用流延工艺结合热压成型及两步烧结来实现(0.99-x)KNNS-0.01CZ-xBKH陶瓷的织构化,简单可行。采用此材料组成和制备工艺制备的无铅压电陶瓷具有高度的晶粒取向性及超高的压电性能从而克服了铌酸钾钠基压电陶瓷压电性能普遍偏低难以满足器件和设备中实际应用的困难。

具有超高压电响应的无铅压电陶瓷材料的制备方法,采用以下步骤:
1)制备基料:以分析纯K2CO3,Na2CO3,Nb2O5,Sb2O3,CaZrO3,ZrO2,Bi2O3,HfO2为原料,按照化学式(0.99-x)KNNS-0.01CZ-xBKH称量、球磨18-24h、在温度850-900℃的条件下预烧3-6h、二次球磨18-24h、烘干、过筛得到混合粉料;
2)制备模板:运用双重熔盐法制备具有高长径比的片状NN模板;
3)将步骤1)得到的基料与步骤2)得到的模板按一定的化学计量比配料混合,加入2倍于粉体的质量的锆球,然后加入体积比为1:1的丙酮和乙醇作为共同溶剂,辊磨12-15小时后再加入有机粘结剂继续辊磨3-5小时,制得具有粘性和流动性的浆料;
4)将步骤3)得到的浆料,使用流延刮刀在玻璃板上进行流延,流延后平放静置,待湿膜干燥后用刀片将膜片从玻璃板上刮下;将膜片切割后叠片并热压成型;
5)将步骤4)得到的陶瓷坯体采用两步烧结工艺进行烧结成瓷,即首先快速升温至1120℃-1150℃,然后急速冷却至1090℃-1100℃,在此温度下保温3-5小时,随炉冷却后即可得到陶瓷样品;
6)将步骤5)得到的陶瓷样品两面被上银电极并在20-30kV/cm的直流电场下极化20-30分钟,得到高压电系数的铌酸钾钠基无铅压电陶瓷。
步骤2)具体采用以下步骤:
2-1)选用高纯Bi2O3,K2CO3,NbO5为原料按照摩尔比为6.5:7:10称量后加入NaCl作为熔盐,NaCl的质量为Bi2O3,K2CO3,NbO5的总质量的1.1倍;
2-2)将上述粉体球磨均匀后在1050℃-1100℃烧结,将得到的粉体用去离子水清洗后得到Bi2.5Na3.5Nb5O18的片状前驱体;
2-3)将Bi2.5Na3.5Nb5O18、K2CO3和NaCl粉体混合球磨后在970-1000℃保温烧结2h,其中Bi2.5Na3.5Nb5O18和K2CO3的物质的量之比为1:1.75,NaCl的质量是Bi2.5Na3.5Nb5O18和K2CO3总质量的1.1倍;
2-4)将烧结后的粉体用去离子水和稀硝酸冲洗多次直到未检测到Cl-和Bi3+的存在,即制备得到片状NN模板。
步骤3)中将基料与模板按照摩尔比为(99~90):(1~10)的比例混合。
步骤3)中加入的有机粘结剂为市售的LS粘结剂。
步骤3)中加入的有机粘结剂和基料的质量比为1:1。
步骤3)制备得到的浆料具有一定的粘性和流动性,其流动性要求其浆料在刮刀的作用下能自然的铺展平整。具有一定的粘性是为了保证刮膜的过程中膜不会断裂。
与现有技术相比,本发明具有以下优点:
1、本发明制得的铌酸钾钠基无铅压电织构陶瓷的织构度高达95%-98%,在室温下非常容易极化,即在极小的直流电压5kV/cm极化即可获得500pC/N以上的压电系数,且在20kV/cm的电压极化后压电系数d33可以高达704±8pC/N,超高的压电性能主要得益于此组分存在有利于极化的多晶型相界以及超高的晶体取向度。
2、本发明制得的铌酸钾钠基无铅压电陶瓷利用两步烧结工艺后具有较宽的成瓷温度(约15℃的成瓷温区)。宽的烧结温区主要是由于在第一步设置的温度处形成了一定的液相,该液相可以以NN模板为晶种在两步温度差的驱动力下外延生长。在第一步得到一定的液相的情况下第二步设置的降低的温度只是提供了一个温度差异的结晶驱动力,所以对第二步的温度要求并没有很苛刻,这是获得较宽的烧结温区的主要原因。
3、本发明制得的铌酸钾钠基无铅压电陶瓷在具有较高的压电性能的同时具备较高的居里温度,拓宽了压电陶瓷的应用温度区间。
4、本发明使用的流延技术制备成本低、工艺简单、化学成分易于精确控制适合大批量的工业化生产。
5、本发明制备的(0.99-x)KNNS-0.01CZ-xBKH织构化无铅压电陶瓷材料可广泛应用于换能器、传感器及驱动器等电子设备中。

2)制备模板:运用双重熔盐法制备具有高长径比的片状NN模板,NN为NaNbO3;
3)将步骤1)得到的基料与步骤2)得到的模板按一定的化学计量比配料混合,加入2倍于粉体的质量的锆球,然后加入体积比为1:1的丙酮和乙醇作为共同溶剂,辊磨12-15小时后再加入有机粘结剂继续辊磨3-5小时,制得具有粘性和流动性的浆料;
4)将步骤3)得到的浆料,使用流延刮刀在玻璃板上进行流延,流延后平放静置,待湿膜干燥后用刀片将膜片从玻璃板上刮下;将膜片切割后叠片并热压成型;
5)将步骤4)得到的陶瓷坯体采用两步烧结工艺进行烧结成瓷,即首先快速升温至1120℃-1150℃,然后急速冷却至1090℃-1100℃,在此温度下保温3-5小时,随炉冷却后即可得到陶瓷样品;
6)将步骤5)得到的陶瓷样品两面被上银电极并在20-30kV/cm的直流电场下极化20-30分钟,得到高压电系数的铌酸钾钠基无铅压电陶瓷。
2.根据权利要求1所述的具有超高压电响应的无铅压电陶瓷材料的制备方法,其特征在于,步骤3)中所述基料与模板的摩尔比为(99~90):(1~10)。
3.根据权利要求1所述的具有超高压电响应的无铅压电陶瓷材料的制备方法,其特征在于,步骤3)中加入的有机粘结剂与基料的质量比为1:1。
4.根据权利要求1所述的具有超高压电响应的无铅压电陶瓷材料的制备方法,其特征在于,步骤3)制备得到的浆料对流动性的要求是浆体在刮刀的驱动下能平整的铺展在玻璃板上,对粘性的要求是在后期的刮膜过程中不会使膜断裂。
