In this article, ytterbium and erbium oxides are used as doping materials for barium titanate (BaTiO3) materials. The amphoteric behavior of these rare-earth ions leads to the increase of dielectric permittivity and decrease of dielectric losses. BaTiO3 ceramics doped with 0.01-0.5 wt% of Yb2O3 and Er2O3 were prepared by conventional solid-state procedure and sintered at 1320°C for 4 h. In BaTiO3 doped with a low content of rare-earth ions (0.01 wt%) the grain size ranged between 10 and 25 μm. With the higher dopant concentration of 0.5 wt%, the abnormal grain growth is inhibited and the grain size ranged between 2 and 10 μm. 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. © 2009 The American Ceramic Society.
