摘要

Nano-sized barium titanate (BT) cubes were synthesized by using a hydrothermal method with an aqueous Ti compound. tert-Butylamine was used as an activation agent to expedite precursor hydrolysis. Oleic acid was employed as a surfactant. The concentrations of the raw materials were found to have a very important effect on tailoring the size and the morphology of the BT nanocubes. The size of the nanocubes varied from 15 nm to 30 nm, and the size distribution was relatively narrow. The surface condition and the size of the BT nanocubes were related to the molar ratios of oleic acid to tert-butylamine. High molar ratios resulted in BT nanocubes with rough surfaces.
