AB  - In this article, ytterbium and erbium oxides are used as doping materials for barium titanate (BaTiO(3)) materials. The amphoteric behavior of these rare-earth ions leads to the increase of dielectric permittivity and decrease of dielectric losses. BaTiO(3) ceramics doped with 0.01-0.5 wt% of Yb(2)O(3) and Er(2)O(3) were prepared by conventional solid-state procedure and sintered at 1320 degrees C for 4 h. In BaTiO(3) doped with a low content of rare-earth ions (0.01 wt%) the grain size ranged between 10 and 25 pm. With the higher dopant concentration of 0.5 wt%, the abnormal grain growth is inhibited and the grain size ranged between 2 and 10 mu m. The measurements of capacitance and dielectric losses as a function of frequency and temperature have been carried out in order to correlate the microstructure and dielectric properties of doped BaTiO(3) ceramics. The temperature dependence of the dielectric constant as a function of dopant amount has been investigated.

AB  - In this article the additives Yb and Er oxides are used as doping materials for BaTiO3-based multilayer devices. The amphoteric behavior of these rare-earth ions leads to the increase of dielectric permittivity and decrease of dielectric losses. BaTiO3-ceramics doped with 0.01 up to 0.5 wt % of Yb2O3 and Er2O3 were prepared by conventional solid state procedure and sintered up to 1320 degrees C for four hours. In BaTiO3 doped with a low level of rare-earth ions the grain size ranged from 10-60 mu m. With the higher dopant concentration the abnormal grain growth is inhibited and the grain size ranged from between 2-10 mu m. The measurements of capacitance and dielectric losses as a function of frequency and temperature have been done in order to correlate the microstructure and dielectric properties of doped BaTiO3-ceramics. The temperature dependence of the dielectric constant as a function of dopant amount has been investigated.

AB  - Doped barium-titanate ceramic is attracting much interest for its application as resistors with a positive temperature coefficient of resistivity (PTCR), multilayer ceramic capacitors (MLCC), thermal sensors etc. In this article the influence of Yb2O3, Er2O 3 and Ho2O3 on microstructure development and dielectric properties of BaTiO3 ceramics has been presented. BaTiO3-ceramics doped with 0.5 up to 1 wt % of Yb2O 3, Er2O3 and Ho2O3 were prepared by conventional solid state procedure and sintered up to 1320°C for two hours. Microstructure investigations of doped BaTiO3 was performed using the scanning electron microscopy (SEM), energy dispersive spectrometer (EDS) and stereological methods. The measurements of capacitance and dielectric losses as a function of frequency and temperature were evaluated by matching model. Special attention has been focused on the study of the changes in morphology, grain and pore size distribution of the sintered specimens and their correlation with the change of capacity, dielectric permittivity and Curie temperature.
