Abstract
Barium titanate (BaTiO3; BT) nanoparticles were synthesized via a sol–hydrothermal microwave method, which were tetragonal phase of BT nanoparticles with an average diameter of ~50 nm. The alkalinity of the initial hydrothermal solution considerably influenced the morphologies of the BT powders. Small amount of hollow and ring-like structure was observed at 5 M. The evolution of the time-dependent morphology revealed a possible formation mechanism. An aggregation, re-alignment, and ripening process is proposed to elucidate the formation of nanoparticles with different morphologies.
