Study of the effect of high electronic excitations in quasicrystals irradiated with heavy ions
We have studied the effect of irradiation with 900 MeV Pb and 780 MeV Xe ions on quasicrystals Al62Cu25.5Fe12.5 and the related cubic α-phase Al55Cu27Fe11Si7. The fluences ranged from 1010 to 5.8 × 1013 ions/cm2. Irradiations ...
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 ...
