Abstract

High purity tetragonal BaTiO3 powders were synthesized by a composite-hydroxide-mediated approach at low temperature using a novel hydrothermal reaction apparatus with a rolling system. The optimum synthesis conditions were explored, and the obtained samples were characterized by their XRD, TEM, TG-DTA and SEM. The powders with an average size of 150 nm in diameter were sintered to almost full theoretical density (ca. 99%) at 1200 °C for 5 h and the obtained ceramics presented a high dielectric constant (9500 at the Curie temperature).
