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 describe d in detail. Powders ave characterized by several methods such as R-ra y diffraction, scanning and transmission electron microscopy, thermogr avimetric measurements and infra-red absorption and X-photoelectron sp ectroscopies. Residual carbon content is quantified by nuclear technic s and Rosenmount method, Raw powders contain small quantities of bariu m carbonate and residual carbon.
