摘　　要：光固化3D打印技术在制备异形压电陶瓷方面具有广阔的应用前景。本文采用数字光处理技术制备了钛酸钡(BaTiO3)压电陶瓷,研究了坯体形貌、烧结温度对钛酸钡微观结构的影响。结果表明,曲拉通X-100的引入使陶瓷料浆的黏度小于3 Pa·s,同时陶瓷粉体的引入未改变树脂的性质。陶瓷坯体层间结合良好,且无明显缺陷。烧成后的BaTiO_(3)陶瓷内部含有四方与正交两种晶相,剩余极化强度为27.6μC/cm^(2),矫顽场为4.6 kV/cm,相对介电常数为2512,介电损耗为0.0091,居里温度为167℃,介电常数为182 pC/N。Stereolithography 3D printing technology has broad application prospects in the preparation of special-shaped piezoelectric ceramics.In this paper,barium titanate(BaTiO3)piezoelectric ceramics were prepared by digital light processing technology.The effects of green body morphology and sintering temperature on the microstructure of barium titanate were studied.The results show that the introduction of Triton X-100 makes the viscosity of ceramic slurry less than 3 Pa·s,and the introduction of ceramic powder does not change the properties of resin.The bonding between the layers of ceramic green body is good,and there are no obvious defects.The BaTiO_(3)ceramics after sintering contains tetragonal and orthorhombic phases.The remanent polarization is 27.6μC/cm^(2),the coercive field is 4.6 kV/cm,the relative dielectric constant is 2512,the dielectric loss is 0.0091,the Curie temperature is 167℃,and the dielectric constant is 182 pC/N.
