Preparation and properties of ferroelectric BaTiO3 thin films produced by the polymeric precursor method
(2000-08-01)
Ferroelectric barium titanate thin films were produced by the polymeric precursor method. In this technique, the desired metal cations are chelated in a solution using a hydroxycarboxylic acid as the chelating agent. Barium ...

Thermal analysis applied in the crystallization study of SrSnO3
(Springer, 2009-07-01)
SrSnO3 was synthesized by the polymeric precursor method with elimination of carbon in oxygen atmosphere at 250 A degrees C for 24 h. The powder precursors were characterized by TG/DTA and high temperature X-ray diffraction ...
Effect of Fe3+ Doping in the Photocatalytic Properties of BaSnO3 Perovskite
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2017-01-01)
In the last ten years, stannates with perovskite structure have been tested as photocatalysts. In spite of the ability of perovskite materials to accommodate different cations in its structure, evaluation of doped stannates ...
Lanthanum-based perovskites obtained by the polymeric precursor method
(Springer, 2008-01-01)
Cobalt oxides, specially the ones with perovskite structure, are of a high technological interest, due to their interesting optical, electrical and magnetic properties. La(1 -x)Ca(x)CoO(3) powder samples were synthesized ...
