Highly anisotropic single crystal-like ceramic of La2Ti2O7 was successfully prepared by an effective 2-D grain alignment using both seed crystals and magnetic field alignment during slip casting followed by templated grain growth (TGG). It was found that the highest magnetic susceptibility is in the [00l] direction of LTO. The grain orientation factors of the three directions for the textured ceramic were calculated as 0.76, 0.71, and 0.73, respectively. The dielectric and ferroelectric properties of the textured ceramic were found to be single crystal like. The dielectric permittivity of the aligned ceramic in the different directions is higher than for single crystal due to contributions from domain walls and grain boundaries.
