Abstract

Nanoparticles of barium carbonate (BaCO~3~) have been synthesized in situ from barium chloride by the slow release of carbon dioxide by alkaline hydrolysis of diethyl carbonate, and stabilized by cetyltrimethylammonium bromide (CTAB) at the water/hexamethylene interface. Transmission electron microscopy, Fourier transform infrared spectroscopy and X‐ray powder diffractometry were used to characterize the products. The results indicate that spherical BaCO~3~ nanoparticles are obtained with poor crystallinity and diameters ranging from 30 to 300 nm. The possible formation mechanism of the nanoparticles at the interface is discussed. (Β© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
