Description
技术领域
本发明涉及无铅压电材料技术领域，尤其涉及一种用于燃气点火的无铅压电陶瓷及其制作工艺。
背景技术
压电陶瓷作为一类重要的功能陶瓷，在电子信息、超声换能、传感器、无损检测等技术领域已获得广泛应用。压电材料及器件具有实现电能与机械能直接转换的功能，其原理是利用正压电效应，当压电瓷柱沿极化方向受到挤压或冲击力时，将受到压缩产生形变，从而致使瓷柱两端表面出符号相反的束缚电荷；产生的电荷经过导线流动在电极间隙发生放电火花，从而点燃可燃性气体，火花能量越大，点燃率越高。压电材料不仅用途广泛，而且其相关材料科学与应用技术的研究一直经久不衰。
锆钛酸铅陶瓷（PZT）是一种目前在压电技术领域应用最为广泛的功能陶瓷材料，主要用在点火器上将机械力转换为电火花来点燃可燃性气体。对于锆钛酸铅陶瓷材料，其烧结温度一般在1150～1300℃之间，有时甚至更高，生产过程能耗较大；另外，烧结过程中氧化铅（PbO）的挥发会严重污染环境，同时也会造成组份的偏差，影响压电性能。为了减轻环境污染和节约能源，多年来人们一直对含铅压电陶瓷特别是在日用生活领域的替代方案进行研究。目前，铋层状结构钛酸盐、钙钛矿结构钛酸盐、铌酸盐等材料因具有相对较好的压电性能成为人们研究的焦点。其中，铌酸盐中的(K0.5Na0.5)NbO3铌酸钾钠（KNN）基无铅压电陶瓷，由于其居里温度高(Tc＝420℃)、介电常数低、压电常数和机电耦合系数高等特性，被认为是一种很有前途取代PZT的压电材料。
与传统的PZT相比, 未掺杂的K0.5Na0.5NbO3陶瓷的结构较为复杂，关于铌酸钾钠（KNN）基陶瓷的文献中多次出现XRD晶面指数混乱的情况。近些年，大量的研究结果表明Li、Ta等元素的掺杂会改善陶瓷的压电性能,其根本原因是晶体结构的改变,进而提高KNN基陶瓷的压电性能。找到合适的元素进行掺杂，并通过合适的方式添加，是提高KNN基陶瓷压电材料压电性能的关键。
发明内容
针对以上问题，本发明提出一种用于燃气点火的无铅压电陶瓷及其制作工艺，用镍、锰和钙元素进行掺杂取代，以及复合添加的方法，实现价态和缺位补偿，活化压电畴，提高压电材料的压电性能，从而在铌酸钾钠基无铅压电陶瓷中实现高的点火电压。
为实现以上目的，本发明通过以下技术方案来实现：一种用于燃气点火的无铅压电陶瓷，化学组成通式为：（KaNabCa1/2-a/2-b/2）(Nb1-c-dCo5c/3Mn5d/4)O3，其中，a，b，c，d为摩尔百分比， 0.3≤a≤0.5，0.3≤b≤0.5，0≤c≤0.1，0≤d≤0.2。
优选的，其原料包括：碳酸钾、碳酸钠、五氧化二铌和辅料；所述辅料为三氧化二钴、二氧化锰和碳酸钙。
本发明在合成铌酸钾钠基无铅压电陶瓷的时，采用对铌酸钾钠基陶瓷A位和B位离子掺杂改性的方法，活化晶格，不仅可以有效改善铌酸钾钠基无铅压电陶瓷的烧结特性，获得高致密度的陶瓷体，还能显著提高铌酸钾钠基无铅压电陶瓷整体的压电性能。
一种用于燃气点火的无铅压电陶瓷的制作工艺，包含以下步骤：
（a）按通式中的摩尔配比称量所述原料，混合无水乙醇，搅拌磨浆，得到浆料；
（b）将浆料压滤成块，放入烧结炉中，在900-950℃下保温预烧10-15h，得到预烧料；
（c）将预烧料干压成型，在950-1000℃的气氛烧结炉中，保温保压烧结6-12h，得到烧结陶瓷；
（d）将烧结陶瓷放到研磨机中抛光，得到尺寸一致、表面光滑的圆柱形陶瓷，然后在圆柱形陶瓷两端的表面镀上一层厚度为0.1±0.01mm的纯银，继续在550-650℃的烧结炉中保温烧结25-35min，得到圆柱形镀银陶瓷；
（e）将圆柱形镀银陶瓷置于电场中极化，得到用于燃气点火的无铅压电陶瓷。
优选的，步骤（e）所述极化过程为：在圆柱形镀银陶瓷其中的一端镀银面上做电极标识，按标识一致的方向将100个以上的圆柱形镀银陶瓷并联排列在极化槽夹上，极化槽夹放入50℃～80℃的硅油中，并对所述的圆柱形镀银陶瓷加3kV/mm～5kV/mm的高压电场，极化30分钟，得到所述用于燃气点火的无铅压电陶瓷。

本发明通过热压烧结来制备铌酸钾钠基无铅压电陶瓷，提高晶体的传质速度，改善压电陶瓷的均匀化和致密化，进而提高压电陶瓷的致密度。通过掺杂多种元素或者化合物，可以显著提升铌酸钾钠基无铅压电陶瓷的压电性能，但负面效果是造成烧结温度过高。当温度超过1000℃，铌酸钾钠陶瓷在烧结过程容易产生大量液相，从而导致晶粒异常长大，异长长大晶粒的存在会降低陶瓷的机械力学性能，最终在实际应用中影响器件的使用寿命。另外，当温度高于1000℃时，碱金属元素钾和钠特别容易挥发，从而导致铌酸钾钠基陶瓷的性能衰减。本发明通过加入适宜的辅料，优化工艺路线，将铌酸钾钠的烧结温度控制在950-1000℃，提高了烧结过程的稳定性，得到的无铅压电陶瓷瞬时点火点电压高，使用寿命较长。
本发明的优先在于：
（1）本发明得到的铌酸钾钠基无铅压电陶瓷用于燃气点火材料，实现了对现有锆钛酸铅陶瓷的替换，有效避免了铅污染。
（2）本发明制备铌酸钾钠基无铅压电陶瓷的过程中，按合适的比例添加含有钴、锰和钙元素的辅料，将铌酸钾钠的烧结温度控制在1000℃下，避免烧结过程出现大量液相，减少钾钠金属的挥发，活化压电畴，提高铌酸钾钠基无铅压电陶瓷的点火电压。
（3）传统的锆钛酸铅陶瓷的瞬时点火电压为8000V，点火寿命在30000次以内，本发明得到的铌酸钾钠基无铅压电陶瓷的瞬时点火电压在10000V以上，且寿命在100000次以上。
（4）传统极化后的含铅压电陶瓷压电常数d33在400pC/N左右，无铅的压电陶瓷只有150pC/N左右，本发明铌酸钾钠基无铅压电陶瓷压电常数d33可以达到400pC/N左右。
