    Abstract

    Li-doped BaTiO3 particles with the Li+ mole fraction, x, of 0-0.06 were synthesized by a solvothermal approach at 200°C. The products consisted of nanoparticles of 50-100nm in diameter. The sinterability and piezoelectric property of Li-doped BaTiO3 were improved by doping with Li ion, i.e., the Li-doped BaTiO3 samples could be sintered to almost full theoretical density (>95%) at a low temperature such as 1100°C, and the highest piezoelectric constant, d33 (260pC/N) and electromechanical coupling factor, kp (43.7%) could be realized at x value of 0.03. The Curie temperatures of all samples were around 130°C, and did not change very much depending on the amount of Li-doping.
