Barium titanate composite ceramic slurry for mold-free direct-writing 3D printing as well as preparation method and application of barium titanate composite ceramic slurry
The invention discloses barium titanate composite ceramic slurry for mold-free direct-writing 3D printing as well as a preparation method and application of the barium titanate composite ceramic slurry, and belongs to the technical field of material preparation and additive manufacturing. The composite ceramic slurry is prepared from the following components in percentage by weight: 70 to 88 percent of BaTiO3 powder, 1.5 to 3.5 percent of binder and the balance of deionized water. Three-dimensional forming of the composite slurry is achieved through the mold-free direct-writing 3D printing technology, and the structure is strengthened through the subsequent sintering process. The obtained ceramic slurry has the advantages of being high in loading capacity and simple and easy to prepare, the requirement for direct forming of 3D printing is met, the variety of 3D printing materials is expanded, ceramic densification of a sintered printing sample is achieved, the sintered printing sample has high strength and high dielectric constant, a complete structure is kept, and the ceramic slurry can be applied to 3D printing. The material can be applied to electromagnetic wave modulation devices, electromagnetic shielding, piezoelectricity and capacitor materials.
本发明公开了一种用于无模直写3D打印的钛酸钡复合陶瓷浆料及其制备方法和应用，属于材料制备和增材制造技术领域。该复合陶瓷浆料按重量比例计的组成为：BaTiO3粉体为70‑88％，粘结剂为1.5‑3.5％，去离子水为余量。利用无模直写3D打印技术实现复合浆料的三维成型，利用后续的烧结过程强化结构。本发明所得的陶瓷浆料具有负载量高和简单易制备的优势，符合3D打印直接成型的需求，扩展了3D打印材料的种类，并且经过烧结后的打印样品实现了陶瓷致密化，使其具有高的强度及高介电常数，并且保持较为完整的结构，可以应用于电磁波调制器件、电磁屏蔽、压电和电容器材料。
