Characterization of BaTiO3 Powder Obtained by a Chemical Route.

The citric resin method is used to prepare stoichiometric, homogeneous and fine barium titanate powders. The elaboration process is described in detail. Powders are characterized by several methods such as R-ray diffraction, scanning and transmission electron microscopy, thermogravimetric measurements and infra-red absorption and X-photoelectron spectroscopies. Residual carbon content is quantified by nuclear technics and Rosemount method, Raw powders contain small quantities of barium carbonate and residual carbon.
