Grain oriented titania ceramics made in high magnetic field

Microstructure with grain orientation has a high potential for greatly improving characteristics of ceramics. This paper shows a very promising approach for developing the structure of grain orientation through para- and dia-magnetic interaction of ceramics particles in an extremely strong magnetic field. We used titania as a raw material. Grain oriented titania ceramics of high density was successfully developed through a processing in a high magnetic field. X-ray diffraction shows that the c-axes of particles of fine powder particles were oriented parallel to the applied magnetic field. The orientation factor is 0.05 as determined using the Lotgering method. High density was achieved by the subsequent sintering. Relative density is 98% of theoretical density.
