抄録
Grain-oriented Nd-modified bismuth titanate (BNIT) ceramics with the a-b-plane perpendicular to the direction of magnetic field (MF) were successfully fabricated by applying MF-assisted forming at lower field strengths. A BNIT powder, in which 25%of the Bi3+-site were substituted with Nd3+, was synthesized by coprecipitation in an alkaline solution and successive calcination at 600°C. Green compacts of the BNIT powder were formed by applying various MF strengths (212 T) during slip casting and then sintered at 900 and 1000°C for different times. The cation substitution with Nd3+ allowed very fine BNIT particles in a slurry to be magnetically aligned at lower field strengths. For BNIT ceramics sintered at 1000°C, the degree of grain orientation increased with increasing MF according to the parabolic relationship. Additionally, the grain orientation was enhanced by the preferential growth of anisotropic BNIT grains occurring at later stage of the sintering.
