Preparation and dielectric property of (Li_0.12Na_0.88)NbO₃-based solid solutions

Abstract

Three solid solution systems (LNN – BaTiO₃ (BT), BaZrO₃(BZ), K_0.5Ba_0.5Ti_0.5Nb_0.5O₃(KBTN)) based on (Li_0.12Na_0.88)NbO₃(LNN) were prepared by conventional solid state reaction. No single phase solid solution was observed in LNN-BT system. In LNN-BZ and LNN-KBTN systems single phase solid solutions with the hexagonal cell were formed in the range of x ≤ 0.5. The length of the a-axis increased with content of BZ or KBTN and that of the c-axis was almost unchanged except x = 0.1 for LNN-BZ.
