Preparation method of piezoelectric ferroelectric ceramic material based on 3D printing technology
The invention discloses a preparation method of a piezoelectric ferroelectric ceramic material based on a 3D printing technology. The preparation method comprises the following steps: step 1, preparing lead-based or lead-free piezoelectric ferroelectric ceramic pre-sintered powder; step 2, preparing 3D printing piezoelectric ferroelectric ceramic slurry from the lead-based or lead-free piezoelectric ferroelectric ceramic pre-sintered powder and adding a template accounting for x% of of the ceramic pre-sintered powder, wherein x is larger than 1 and smaller than or equal to 5; step 3, realizing directional arrangement of the template in the powder through a 3D printing photocuring process so as to prepare a 3D-printed piezoelectric ferroelectric ceramic green body; and step 4, degreasing and sintering the 3D-printed piezoelectric ferroelectric ceramic green body to obtain the piezoelectric ferroelectric ceramic material with a texture degree based on the 3D printing technology. According to the method, the mode of scraping via a scraper in a 3D printing process is applied to the directionally-arranged template, and the template with a certain size can be transversely distributed in each layer of the cured green body, so the preparation method of piezoelectric ferroelectric textured ceramic is not limited to a traditional tape casting method any more.
本发明公开了一种基于3D打印技术的压电铁电陶瓷材料的制备方法，包括以下步骤：步骤1、制备铅基或无铅压电铁电陶瓷预烧粉体；步骤2、将所述铅基或无铅压电铁电陶瓷预烧粉体制成3D打印压电铁电陶瓷浆料，并加入陶瓷预烧粉体x％的模板，1＜x≤5；步骤3、通过3D打印光固化工艺，实现模板在粉体中的定向排列，制备得到3D打印压电铁电陶瓷生坯；步骤4、将3D打印压电铁电陶瓷生坯进行脱脂、烧结，得到所述的基于3D打印技术的具有织构度的压电铁电陶瓷材料。本发明实现了将3D打印工艺中刮刀刮平的方式运用于定向排列模板，能够将一定尺寸的模板横向分布在每层固化的坯体中，使压电铁电织构陶瓷的制备方法不再限于传统的流延法。
