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  - In the present paper the microstructure and domain structure in modified BaTiO3 with Pb and Ca as additives have been investigated using SEM technique. The (Ba,Pb)TiO3 and (Ba,Ca,Pb)TiO3 ceramics show a slight difference in grain size, being smaller in composites with Ca additives which acts as gl ain growth inhibitor. The domain configuration is almost the same. The small grain microstructure with tiny domains have been observed in specimen sintered at 1300 degrees C and the average grain size is in the range 1-3 mu m. For those specimens sintered at 1320 degrees C the homogenous microstructure is also obtained with grain size around 2-4 mu m. For both types of specimens, the single domain structure is associated with grain which size is lower than 2 mu m. The banded domain structure could be observed in grains with size bigger than 3 mu m. The bar shape grains and elongated grains together with some large region in microstructure are free of domain structure. The observed domain patterns reveal mainly the straight domain boundary lines with 90 degrees domains walls. The wall thickness ranged from 0.03 mu m to 0.15 mu m, while the domain width is in the range of 0.1 mu m-1 mu m.
