Abstract

Monodispersed barium zirconate (BaZrO₃) fine particles with a spherical shape have been synthesized by hydrothermal reactions using barium hydroxide and a Zr-triethanolamine (TEOA) complex. The particle mean diameter was gradually controlled in a range from 0.20 μm to 3.5 μm by change in the added amount of seed nanoparticles. The mechanistic characterization of the seed-mediated BaZrO₃ sphere synthesis revealed that the particle growth obeyed a simple seed growth mechanism. In the present system, utilization of the Zr-TEOA complex played an important rule to prevent uncontrollable nucleation to form the uniform BaZrO₃ fine particles with narrow size distributions.
