Abstract
The thermal decomposition of barium bis(citrato)oxolitanate citrate he ptahydrate, a molecular precursor of BaTiO3 fine powders is studied by temperature-dependent x-ray powder diffraction and thermogravimetry. A thorough investigation of the dehydration stage is presented. Three crystalline phases containing seven, three, and two water molecules, r espectively, are identified from their powder diffraction pattern. The results of pattern indexing are presented and discussed in terms of p arameter relationships. (C) 1997 International Centre for Diffraction Data.
