Abstract: Ceramic particles with magnetic anisotropy can be oriented under the function of magnetic field, and textured microstructure can be formed in the sintered ceramics. The application of this technology is important for further promoting the properties and development of ceramics. The texturization behavior of ceramic is affected by particle size and sintering time. Therefore, in this study, SiC green ceramics are prepared by gel-casting assisted by magnetic alignment technology, and textured SiC sin- tered ceramics are prepared at 1 950 ℃ with no magnetic field or pressure. The effects of SiC particle size and sintering time on the texturization behaviors and densifications of SiC green and sintered ceramics are analyzed. Results showed that c-axis of SiC grains is oriented to align along the magnetic field direction. With the increasing ratio of SiC particles with large size, the Lotgering factor of green ceramics increases from 0.84 to 0.92, which is the result that the SiC particles with big size are easily oriented under same magnetic field intensity. After sintered at 1 950 ℃, textured microstructure is formed in the sintered ceramics with the c-axis of SiC grains oriented. With the increasing ratio of SiC particles with large size, the Lotgering factor of sintered ceramics first increases and then decreases, and the maximum could reach to 0.95. However, owing to the densification difficulty of large particles, the relative density of sintered ceramics shows a decreasing trend. With the suitably increasing of the sintering time, the degree of texture and densification gradually increases. As a result, the optimization of particle size ratio and sintering parameters can play an important role in improving the texturization behavior of ceramics.
