Description
技术领域
本发明属于压电陶瓷材料领域,具体涉及应用于高温压电能量收集器件的,在400℃超高温下具有高压电电荷常数和高能量收集性能的陶瓷材料及其制备方法。
背景技术
随着无线传感网络(WSN)系统的发展,低功耗微传感设备得到了迅速发展和广泛应用,但是随之而来的数量庞大的供电电池的更换将造成昂贵的维护成本和巨大的资源浪费。特别是在一些特殊领域,如航空航天、核反应堆、地热能源等高温服役环境中,供电电池的不定期更换将付出巨大代价,实现高温微器件的自供电具有重要的现实意义。压电能量收集器件可高效地将环境中废弃的振动能回收再利用,被认为是微功率电力供应无线传感网络中最有可能替代传统电池实现为WSN长期供电的能量转换装置。
目前,商业化应用最广泛的压电材料是Pb(Zr,Ti)O3(简称PZT)体系材料,其居里温度约为180~386℃,但实际安全使用温度被限制在200℃以下,温度过高就会出现性能的严重劣化,大大限制了其在高温环境的应用。而钙钛矿结构BiScO3-PbTiO3(简称BS-PT)材料,具有高居里温度且压电活性高,是高温压电陶瓷研究的主要材料体系。然而由于其退极化行为发生在400℃之前,在400℃及以上的超高温度环境中也无法应用。因此,研制出在400℃及以上的超高温下仍具有高压电性,且能实现大功率器件化应用的高温压电陶瓷材料一直是人们亟待解决的问题。
本发明中,以BS-PT为基体材料,利用相界理论设计宽组成范围的zBiScO3-xPbTiO3-yBi(Zn0.5Hf0.5)O3三元陶瓷材料体系,通过多重准同型相界(MPB)的构建与筛选,利用传统固相法,制备出在400℃超高温下具有高压电电荷常数值的高温压电陶瓷材料,并实现了高温压电能量收集性能评价。
发明内容
本发明的目的在于提供将一种陶瓷材料作为400℃超高温下具有高压电电荷常数值以及压电能量收集性能的高温压电陶瓷材料的应用及制备方法。
本发明的材料特征在于,作为高温压电陶瓷材料时,陶瓷材料400℃时压电电荷常数d33=726pC/N,可应用于高温领域压电器件。
本发明的材料另一特征在于,将其装配成悬臂梁式(单层)能量收集器时,在400℃高温下,开路电压峰峰值为3.16V,能量密度为0.031μW/mm3,对10μF、16V的商业电解电容器充电40s电容器充满时两端电压为0.9V,可应用于高温领域压电能量收集器件。
为实现上述目的,本发明采取以下技术方案:
一种陶瓷材料的应用,该压电陶瓷材料的化学组成为:zBiScO3-xPbTiO3-yBi(Zn0.5Hf0.5)O3,其中,x,y,z分别表示PbTiO3、Bi(Zn0.5Hf0.5)O3和BiScO3组分的摩尔分数,其中x取值为0.620~0.650,y取值为0.01~0.03,z取值为1-x-y,用于高温(如400℃)领域压电能量收集器件,优选为x=0.635,y=0.01,z=0.355。
上述陶瓷材料400℃超高温时,具有高压电性能,压电电荷常数d33=726pC/N。
上述陶瓷材料装配成悬臂梁式能量收集器,400℃时,开路电压峰峰值为3.16V,能量密度为0.031μW/mm3,对10μF、16V的商业电解电容器充电40s电容器充满时两端电压为0.9V。
本发明上述在超高温下具有高压电性能和能量收集性能的陶瓷材料制备方法,具体包括以下步骤:
(1)将原料Pb3O4、TiO2、Bi2O3、Sc2O3、ZnO和HfO2按压电陶瓷材料中元素化学摩尔比称量,将称量好的原料放入球磨罐中,以无水乙醇为介质置于卧式球磨机中球磨24h,然后在100℃条件下烘干;
(2)将烘干的料在800℃煅烧,具体工艺如下:25℃~650℃,升温速率为7℃/min,650℃~800℃,升温速率为3℃/min,保温2h,随炉冷却至室温。
(3)将煅烧后的粉料加入无水乙醇进行二次球磨24h;
(4)将二次球磨得到的粉料加入粘结剂,在压力下压制成陶瓷素坯,并加热进行排胶处理;
如加入5wt.%的聚乙烯醇(PVA)粘结剂,在100MPa单轴压力下压制成陶瓷素坯,在560℃进行排胶处理2h;
(5)将排胶处理后的素坯体在1150℃烧结,具体工艺如下:25℃~650℃,升温速率为7℃/min,650℃~950℃,升温速率为3℃/min,650℃~1150℃,升温速率为1.5℃/min,保温2h,随炉冷却至室温。
制备得到的陶瓷材料,经过表面的抛光处理,烧渗银电极,在120℃的硅油中,在4kV/mm的电压下极化30min。经室温老化24h后对样品进行电性能的测试。
其中,得到纯钙钛矿结构最佳样品组成为x=0.635,y=0.01,z=0.355。经原位测试,400℃时压电电荷常数d33=726pC/N;将其装配成悬臂梁式能量收集器后,400℃时开路电压峰峰值为3.16V,能量密度为0.031μW/mm3,对10μF、16V的商业电解电容器充电40s电容器充满时两端电压为0.9V。可以满足400℃超高温领域常规微电子器件的供电应用要求。
与现有技术相比较,本发明具有以下优点:
(1)本发明在400℃超高温下仍具有高压电性,原位测试压电电荷常数为726pC/N,比此时基体0.36BiScO3-0.64PbTiO3(简称BS-PT64)的d33值(405pC/N)高出79%,高压电性为高温大功率器件应用提供了保障。
(2)本发明陶瓷材料装配成悬臂梁式能量收集器,在400℃时,开路电压峰峰值为3.16V,能量密度为0.031μW/mm3,对10μF、16V的商业电解电容器充电40s电容器充满时两端电压为0.9V。而此温度下BS-PT64能量收集器的开路电压峰峰值仅为0.72V,而外接负载时则无法工作。证明本发明陶瓷材料是一种潜在的可应用于400℃超高温环境能量收集器件的压电陶瓷材料。
(3)本发明通过工艺制度设计,用卧式球磨机球磨,传统固相法制备,方法简单,效果优异,应用于能量收集器件,便于大规模生产,具有显著的经济和社会价值。
