Structural, dielectric and pyroelectric studies of Pb1−XCaXTiO3 thin films
Thin films of Pb1−xCaxTiO3 [x=0.20, 0.24 and 0.28] have been prepared on ITO coated Corning glass substrates by sol gel technique. The perovskite phase of PCT films is formed at 650 °C with a polycrystalline tetragonal ...
Polymeric citrate precursor route to the synthesis of the high dielectric constant oxide, CaCu3Ti4O12
Using citric acid and ethylene glycol, a polymeric precursor of the above compound was obtained at low temperatures (135 °C) which on subsequent heat treatments led to pure CaCu3Ti4O12 at 1000 °C. On sintering further at ...
Single crystal structure, electrical and electrochemical properties of the quaternary thiospinel: Ag2FeSn3S8
Single crystals of Ag2FeSn3S8 have been obtained by heating pure metals and sulphur in evacuated silica tubes at 750 °C. Structural analysis of Ag2FeSn3S8 by single crystal X-ray diffraction analysis shows that it crystallizes ...
Polymeric citrate precursor route to the synthesis of nano-sized barium lead titanates
Monophasic oxides of the formula, Ba1−xPbxTiO3 (0≤x≤1.0) were obtained at temperatures close to 500 °C from polymeric precursors formed using citric acid and ethylene glycol. These oxides were found to be tetragonal for ...
