研制了一种新型的水基锆钛酸铅（PZT）油墨。利用直写组装技术，用该油墨构建了直径为微米级的木堆结构。流变测试表明，该油墨具有剪切变稀特性。显微形貌和密度测试结果表明，烧结后的样品形成了相对密度较高的陶瓷。X射线衍射（XRD）测试表明，烧结样品的主相为三方晶系PbZr 0. 58 Ti 0. 42 O3。压电常数d33为410 pC/N，表明烧结样品具有良好的压电性能。直写压电陶瓷技术具有可设计性好、成型速度快、成型精度高等优点，为压电材料和器件的设计和应用提供了新的思路和方法。
A novel kind of water based lead zirconate titanate (PZT) ink was developed. Woodpile structures with diameter of micrometer scale were constructed from this ink by using direct write assembly technique. According to the rheological test, the ink shows shear-thinning behavior. Micro-morphology and density test results show that the sintered samples have formed ceramics with high relative density. Measurement of X-ray diffraction (XRD) shows that the main phase of sintered samples is rhombohedral PbZr0.58Ti0.42O3. The value of piezoelectric constant d33 is meas- ured to be 410 pC/N, which shows that the sintered samples exhibit good piezoelectric property. The direct write as- sembly technique has merits of good designability, rapid forming capability and high precision prototyping, which provide new ideas and methods for the design and application of piezoelectric materials and devices.
