BaTiO3 obtained through metallic stearate precursors
(Elsevier B.V., 2003-03-01)
Metallic stearates were used as precursors to obtain BaTiO3. Barium and titanium stearate mixtures were homogenized in ball mill containing some amount of ammonium stearate. The mixture of the precursors was evaluated by ...
Secondary phases in Nb-doped BaTiO3 ceramics
(Elsevier B.V., 2002-01-01)
In this work, the effect of Nb2O5 addition on the microstructure of BaTiO3 was studied. From XRD diagrams, a diminution in tetragonality parameters with an increase in dopant concentration was observed. In order to determine ...

Rietveld analysis of mechanically activated BaCO(3)-TiO(2) system
(J C P D S-int Centre Diffraction Data, 2008-06-01)
BaTiO(3) powders were prepared through mechanical activation chemistry and analyzed by Rietveld refinement with X-ray diffraction data. Raw BaCO(3) and TiO(2) powders were dry milled for 5 and 20 h and then calcinated for ...

Evidence of hetero-epitaxial growth of Pb(Mg1/3Nb2/3)O-3 on the BaTiO3 seed particles of a citrate solution
(Elsevier B.V., 2003-01-30)
Citrate solution was employed in preparing Pb(Mg1/3Nb1/3)O-3 (PMN) powder from polymeric precursors. BaTiO3 particles of 600 nm average size were used as seed for growing PMN. X-ray diffraction (XRD) indicated the presence ...
