Preparation of High Density LiNbO3 Ceramics by Spark Plasma Sintering

Abstract

Abstract: In order to solve the problem of low sintering density caused by low sintering activity of LiNbO₃ powders and loss on ignition of Li element at high temperature, LiNbO₃ powders with stoichiometric ratio were synthesized by solid phase reaction method. The oxygen vacancy concentration of LiNbO₃ powders increased by reduction treatment, and then high density LiNbO₃ ceramics were prepared by spark plasma sintering (SPS) technology. The phase composition, oxygen vacancy concentration and surface morphology of LiNbO₃ powders and the sintered body were characterized and analyzed by XRD, EPR, XPS, Raman spectroscopy and SEM. The results show that the oxygen vacancy concentration of LiNbO₃ powders increases significantly after 700 ℃ reduction treatment, and the oxygen vacancies generate at the lattice position of O atom in Nb—O octahedron. With the increase of SPS temperature, the relative density of LiNbO₃ ceramics shows a trend of increasing first and then decreasing. The relative density of sintered body reaches a maximum of 98.19% at 900 ℃. After annealing and oxygen increasing treatment at 800 ℃, the color of LiNbO₃ ceramics changes from black to white. At the same time, the oxygen vacancy defect of LiNbO₃ ceramics is eliminated and the relative density is 98.32%. This study provides a new idea for the preparation of high density alkali metal niobate ceramics.
