Fabrication methods for textured ceramics have been studied for improving properties of and manufacturing efficiency. Strong magnetic orientation is a key technology for tailoring microstructure of functional materials. Furthermore, it is important that textured microstructure is promoted by subsequent sintering through densification and grain growth processes. We focus on the continuous fabrication processing of both particle-orientation in a magnetic field and development of oriented structure during sintering. Conditions as particle size, magnetic field, and sintering temperature can be optimized for controlling textured microstructures. The mechanism and implication are explained using experimental data here.

为提高织构陶瓷的性能和制造效率，对织构陶瓷的制备方法进行了研究。强磁取向技术是实现功能材料微观结构剪裁的关键技术。此外，重要的是织构组织在随后的烧结过程中通过致密化和晶粒生长过程得到促进。重点研究了在磁场中颗粒取向的连续制备工艺和烧结过程中取向结构的发展。通过优化颗粒尺寸、磁场和烧结温度等条件，可以控制织构组织。文中用实验数据解释了其机理和意义。
