摘要

Barium titanate is among the most important material for applications in electronics and microelectronics due to its excellent ferroelectric, piezoelectric and dielectric properties. It is used as the main constituent in many types of electroceramics such as multilayer capacitors and thermistors. In the present paper some results regarding the influence of the processing conditions on the microstructure and electrical properties of sintered doped BaTiO_3 are presented. Different compositions of doped barium titanate were synthesised using a sol-gel colloidal process. The powder composition has been determined by chemical quantitative analysis and the structure has been detected from the XRD pattern. SEM and EDAX were used to study the effect of pressing and sintering conditions as well as the role of different dopants on the microstructure and morphology. Dielectric loss angle and relative permitivity were calculated based on the impedance measurements. Correlation equations have been proposed in order to calculate the electric properties as a function of processing parameters.
