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 ...
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 ...
