Continuous production of barium titanate fine particles were performed by hydrothermal synthesis process using a green reaction system. The mechanism of particle formation and growth and the feasibility of continuous production of barium titanate particles were also discussed. The separation solution had been reclaimed and recycled as a base solution, after the hydrothermal reaction in this study. This recycled process has been studied at least 9 cycles. The effect of the mineralizer and Ti-precursor material on particle size and its morphology was investigated.
