Description
技术领域
本发明涉及一种压电陶瓷流延浆料，特别是一种锆钛酸钡钙压电陶瓷流延浆料及其应用。
背景技术
压电陶瓷材料已被广泛地应用在航空航天、医疗、生活、军事等各领域。无铅压电陶瓷由于不含铅、不污染环境，符合人类社会可持续发展的要求，因而备受产业界和研究人员的青睐。其中，锆钛酸钡钙(BCZT)基无铅陶瓷体系更是受到广泛关注。
目前，为了提高综合电学性能，通常会采用反应模板生长法(RTGG)，通过流延工艺制备BCZT无铅压电陶瓷。因此，流延浆料的制备就成了工艺关键。根据原料基粉的不同，流延浆料可分为水系和有机系两大类，通过添加各种分散剂、增塑剂、粘结剂、消泡剂等各种添加剂，经过球磨后制备出具有一定粘度的浆料。但是现有电子陶瓷流延浆料由于基粉性质不同，基本都属于专用，而非通用。因此，本体系需要开发一种锆钛酸钡钙压电陶瓷流延浆料。
发明内容
本发明的目的在于，提供一种锆钛酸钡钙压电陶瓷流延浆料及其应用。本发明具有为BCZT基粉料的专用流延配方，用于流延工艺，形成薄膜，以制备高性能BCZT压电陶瓷，且流延薄膜厚度为50微米时，介电常数和压电常数较高，同时烧结温度最低的特点。
本发明的技术方案：一种锆钛酸钡钙压电陶瓷流延浆料，该锆钛酸钡钙压电陶瓷流延浆料是以碳酸钡、碳酸钙、二氧化锆和二氧化钛为基粉原料，以钛酸钡为晶种，以无水乙醇为溶剂，球磨，添加分散剂、增塑剂、粘结剂和消泡剂后，球磨，形成锆钛酸钡钙压电陶瓷流延浆料。
前述的锆钛酸钡钙压电陶瓷流延浆料中，所述基粉原料中碳酸钡、碳酸钙、二氧化锆和二氧化钛的摩尔比为(Ba0.85Ca0.15)(Zr0.1Ti0.9)O3；所述钛酸钡占基粉原料质量的1-10％。
前述的锆钛酸钡钙压电陶瓷流延浆料中，所述分散剂为蓖麻油、磷酸三乙酯或三乙醇胺；所述增塑剂为邻苯二甲酸二丁酯、邻苯二甲酸二辛酯或聚乙二醇；所述粘结剂为乙基纤维素、聚乙烯醇缩丁醛或聚丙烯酸；所述消泡剂为正丁醇。
所述的锆钛酸钡钙压电陶瓷流延浆料的制备方法，包括有以下步骤：
(1)配料：将基粉原料和晶种，分别烘干，备用；
(2)混料：将烘干后的基粉原料和晶种混合，搅拌均匀，得混合料；
(3)混浆：向混合料中加入25-50％的无水乙醇，球磨6-12h，得混浆；
(4)配浆：向混浆中添加分散剂、增塑剂、粘结剂和消泡剂，球磨6-24h，形成锆钛酸钡钙压电陶瓷流延浆料。
前述的锆钛酸钡钙压电陶瓷流延浆料中，所述步骤(4)中，向混浆中添加0.5-5％分散剂、2-8％增塑剂、2-10％粘结剂和0.1-1％消泡剂，球磨6-24h，形成锆钛酸钡钙压电陶瓷流延浆料。
所述的锆钛酸钡钙压电陶瓷流延浆料的应用，将该锆钛酸钡钙压电陶瓷流延浆料用于流延工艺，形成薄膜，制备BCZT压电陶瓷。
前述的锆钛酸钡钙压电陶瓷流延浆料的应用中，所述将该锆钛酸钡钙压电陶瓷流延浆料用于流延工艺，形成薄膜，制备BCZT压电陶瓷，具体包括有以下步骤：
(1)流延：根据锆钛酸钡钙压电陶瓷流延浆料的粘度，在流延机上流延出薄膜料，得流延料；
(2)压制：将流延料利用等静压机压制，剪裁，得待烧结物；
(3)烧结：将待烧结物烧结，随炉自然冷却后取出，得烧结物；
(4)被电极和极化：将烧结物进行被电极和极化处理，得BCZT 压电陶瓷。
前述的锆钛酸钡钙压电陶瓷流延浆料的应用中，所述步骤(1)中，薄膜厚度为50-200微米。
前述的锆钛酸钡钙压电陶瓷流延浆料的应用中，所述步骤(2)中，将流延料利用等静压机在25-60MPa压力下压制成1毫米厚度。
前述的锆钛酸钡钙压电陶瓷流延浆料的应用中，所述步骤(3)中，将待烧结物在1250-1350℃下、保温3-6h烧结，随炉自然冷却后取出。
与现有技术相比，本发明具有以下有益效果：
本发明的锆钛酸钡钙压电陶瓷流延浆料为BCZT基粉料的专用流延配方，可以根据需要，制备出不同厚度的流延薄膜，从而降低陶瓷烧结温度，有效提高锆钛酸钡钙压电陶瓷的综合电学性能。
传统的BCZT压电陶瓷烧结温度一般在1400-1450℃左右，而通过本发明可将烧结温度降低至1250-1350℃左右。且本发明综合电学性能主要体现在可提升压电性能和介电性能，压电常数可达500pC/N以上，介电常数可达13000以上，与现有技术相比可提高性能10-20％。
实验证明：
1、实验方法：
本发明共设置三组实验，第一组为使用本发明实施例1得到的单层200微米厚度的压电陶瓷样品，第二组为使用本发明实施例2得到的单层100微米厚度的的压电陶瓷样品，第三组为使用本发明实施例3得到的单层50微米厚度的的压电陶瓷样品，三组压电陶瓷样品均采用GB/T3389-2008测试标准，分别对四组压电陶瓷样品的烧结温度、介电常数和压电常数进行测试。
2、实验结果：
不同流延厚度的薄膜样品，经过压制、烧结后，压电陶瓷的介电常数和压电常数如图1所示，测试结果记录在表1中，从表1可以看出：流延薄膜的厚度明显影响陶瓷的电学性能，随着流延薄膜厚度的不断降低，压电陶瓷的介电常数和压电常数均有所提高，烧结温度逐渐降低。
表1：三组压电陶瓷样品的实验数据结果对比表
3、实验分析：
综合三组压电陶瓷样品的测试结果分析得出：为了保证介电常数和压电常数较高，同时烧结温度最低，流延薄膜厚度为50微米时最佳。
综上所述，本发明具有为BCZT基粉料的专用流延配方，用于流延工艺，形成薄膜，以制备高性能BCZT压电陶瓷，且流延薄膜厚度为50微米时，介电常数和压电常数较高，同时烧结温度最低的有益效果。
