摘要: 压电陶瓷是电子元器件中的重要材料,其个性化和复杂化制造对提高压电功能器件的性能具有重要意义。然而,由于陶瓷的高脆性和高硬度,传统成形工艺在制备复杂结构时面临较大挑战。增材制造基于逐层叠加原理,理论上可制备任意复杂结构,为压电陶瓷复杂构件的制备提供了新方案。本文采用立体光刻(SLA)增材制造工艺,成功制备了锆钛酸铅(PZT)复杂结构压电陶瓷骨架,研究了浆料固含量对PZT陶瓷浆料流变性能,PZT陶瓷烧结体微观形貌、相对密度及电学性能的影响。结果表明,陶瓷固含量的增加有助于晶粒在高温下的生长以及坯体的致密化,但同时增加了浆料的表观黏度,降低了浆料的固化性能,不利于复杂结构PZT的制备。本研究制备了相对密度为98.26%、压电系数d33为341 pC/N的PZT基陶瓷烧结体,为增材制造高性能压电陶瓷及其复合材料提供了参考。

Abstract: Piezoelectric ceramics are important materials in electronic components, and their individualized and complex fabrication is important to improve the performance of piezoelectric functional devices. However, due to the high brittleness and hardness of ceramics, traditional molding processes face greater challenges in preparing complex structures. Additive manufacturing, based on the principle of layer-by-layer superposition, can theoretically prepare arbitrary complex structures, providing a new solution for the preparation of complex components of piezoelectric ceramics. In this paper, a lead zirconate titanate (PZT) piezoelectric ceramic skeleton with complex structure was successfully prepared using stereolithography (SLA) additive manufacturing process, and the effect of slurry solid content on the rheological properties of PZT ceramic slurry, the microscopic morphology, the relative density, and the electrical properties of PZT ceramic sintered body was investigated. The results show that the increase of ceramic solid content contributes to the grain growth at high temperature and the densification of billet, but at the same time increases the apparent viscosity of slurry and reduces the curing performance of slurry, which is not conducive to the preparation of PZT with complex structure. In this study, PZT-based ceramic sintered bodies with a relative density of 98.26% and a piezoelectric constant d33 of 341 pC/N are prepared, which provides a reference for the additive manufacturing of high-performance piezoelectric ceramics and their composites.
