The Li1+xyNb1−x−3yTix+4yO3 (0.06 ≤ x ≤ 0.33, 0 ≤ y ≤ 0.09) (hereafter LNT), forms a unique and periodical structure in the Li2O-Nb2O5-TiO2 ternary system. In this work, toward application of the unique qualities of an electro-ceramic, we fabricated oriented LNT balk ceramics by slip casting in a strong magnetic field of 12 T using various sizes of particles. The c-axis of the LNT powders was aligned parallel to the magnetic field. As a result, we found anisotropic- and unique- electric properties which were caused by a superstructure with intergrowth layers of corundum-type [Ti2O3]2+. The Qf value parallel to the c-axis was about five times greater than that of perpendicular to the c-axis. We first clarified the mechanism showing that the anisotropic Qf value was caused by the anisotropic electron conductivity and the anisotropic bonding strength in the superstructure.
