各向异性磁化率在弱磁性陶瓷如二氧化钛中非常小；因此，利用磁场形成织构结构是非常困难的。然而，我们在本文中证明，可以通过在高磁场和加热下的滑移铸造来制备有织构的二氧化钛。该悬浮液在高磁场条件下经滑移铸造压实后，得到具有轻微结晶取向的绿色固体。织构程度随温度的升高而增大，晶体织构的发育伴随着晶粒的长大。
Anisotropic susceptibility is very small in feeble magnetic ceramics such as titania; therefore, it had been very difficult to develop a textured microstructure using a magnetic field. However, we demonstrate in this paper, that textured titania can be prepared by slip casting in a high magnetic field and heating. After the suspension was compacted by slip casting in a high magnetic field, a green solid with a slight degree of crystallographic orientation was obtained. The degree of texture increased with increasing temperature, and crystallographic texture development accompanied grain growth in the specimens.
