Preparation, characterization and dielectric properties of CaCu3Ti4O12 ceramics

Effects of rare earth ionic doping on microstructures and electrical properties of CaCu3Ti4O12 ceramics

“…The values of dielectric constant e r of CCTO ceramics were found to be in the range of 10 3 -10 5 , depending on processing conditions. Therefore, CCTO has attracted considerable attention for its potential applications and nature of its dielectric properties since high dielectric constant will lead to miniaturization of capacitive components in electronic devices [1][2][3][4][5]. In addition to their giant dielectric properties, CCTO ceramics can also exhibit non-linear electrical behavior.…”

Modified giant dielectric properties of samarium doped CaCu3Ti4O12 ceramics

“…gained considerable attention due to its abnormal high dielectric constant (e 0 $ 10 3 -10 5 ) over the temperature range from 100 to 600 K and its apparent nonlinear current-voltage (current density-electric field, J-E) properties [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. By considering the dielectric and nonlinear electrical properties of these perovskite-type materials, it is believed that these ceramics are promising materials for many applications.…”

Synthesis of CaCu3Ti4O12 nanofibers by electrospinning

“…The main decomposition of nitrates occurred in this temperature. The last endothermatic peak took place at 417.80 °C which is related to the degradation of PVP, accompanied by more than 44.27% weight loss in TG curve [23]. Most organic materials (PVP, ethanol, methanol, -NO3 groups of nitrates) and other volatiles will degrade at the temperature below 500 °C [19].…”
