Electrical, mechanical and other properties of ceramic materials can be controlled by designing their microstructures. It had generally been difficult to utilize a magnetic field for tailoring the microstructure in feeble magnetic ceramics, such as Al 2 O 3 ; however, the possibility of controlling the microstructure by a magnetic field occurred with the development of superconducting magnets. In this review paper, we introduce a novel processing for the microstructual design in ceramics by colloidal processing in a strong magnetic field and an electric field. We demonstrate that the textured alumina can be fabricated by slip casting in a strong magnetic field and the production of alumina/alumina laminar composites with different crystalline-oriented layers can be achieved by electrophoretic deposition in a strong magnetic field. In order to control the texture using a magnetic field, a good dispersion of powder in a suspension is necessary because a strong attractive force between the agglomerated particles prevents each particle in a suspension from rotating in the magnetic field. The degree of orientation depends on the processing factors, such as heating temperature, viscosity of suspension, etc. And the grain growth in Al 2 O 3 matrix enhances crystallographic texture development. The bending strength of the laminar composite depended on the direction of the multilayered microstructure with alternate crystalline-oriented layers. Crack propagation and fracture mode depend on the direction of microstructure in the laminar composite with controlled crystalline orientation. q

“…Other authors have also considered the influence of conductivity on the deposition in aqueous and non-aqueous systems. 30,58,[63][64][65][66][67][68][69][70][71][72][73][74][75][76] Some of them have demonstrated that a high ionic concentration in the suspension could be deleterious for particle stability, inhibiting the movement of ceramic particles, and thereby decreasing the deposit growth and sometimes its quality. In fact, these studies indicate that electrostatic and electrosteric stabilization in non-aqueous and aqueous media have to be adjusted in order to assure a low ionic concentration in stable suspensions.…”

Hydrothermally synthesized BaTiO 3 was colloidally consolidated by slip casting and by electrophoretic deposition in a high strength magnetic field of 17.4 T. Textured BaTiO 3 was successfully prepared by both processing techniques, with the {001} plane aligning normal to the direction of the magnetic field. The initial alignment in the green powder compact was preserved and enhanced after sintering from 1400 1C to 1500 1C. The sintering temperature hardly influenced the degree of texture in slip cast samples but did influence the grain size of all BaTiO 3 ceramics and the degree of texture in the electrophoretically deposited samples. The BaTiO 3 ceramics processed in the strong magnetic field showed crystallographic texture but not morphological, so the microstructure did not show any anisotropy. The highest Lotgering factor (0.85) was measured for the ceramics made by electrophoretic deposition and sintered at 1500 1C.
