abstract = "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.",
