AB  - In the process of BaTiO3 ceramics consolidation, technological parameters like sintering temperature, pressing pressure and additives significantly determine the microstructure and electrical properties. Slight change of a particular sintering parameter can considerably change the microstructure as well as the electrical parameters. Structural complex grain-contact-grain is observed on Ho doped BaTiO3 ceramics, sintered from 1320 to 1380 degrees C. The new configuration model of ceramic grain contact surfaces is presented in this paper. This model is based on Coble's two-sphere approximation and its generalisation to ellipsoidal geometry. The integral contact surface directly influences the value of the total ceramic capacity. Fractal method is applied for intergrain contact analysis. Ceramic grains are considered to have fractal surface (as it is elsewhere in nature) and, therefore, fractal structure influences on the dielectric properties of BaTiO3 ceramics. The obtained results give better understanding of ceramic microstructure with the final aim to establish significant interrelation among processing, structural and electrical parameters.

AB  - Ferroelectric BaTiO3 as one of the most important ceramics materials in electronic, used on wide range of applications, can be modified with various dopant ions. In this paper, the influence of Er2O3, Yb2O3, Ho2O3 and La2O3, on microstructure, microelectronic and dielectric properties of BaTiO3-ceramics has been investigated. The solid solubility of rare-earth ions in the BaTiO3 perovskite structure has been studied by different methods of structural analysis including SEM-JEOL 5300 and energy dispersive spectrometer (EDS) system. BaTiO3-ceramics doped with 0.01 up to 1 wt% of rare-earth additives were prepared by conventional solid state procedure and sintered from 1320 degrees C to 1380 degrees C for four hours. We also applied the fractal method in microstructure analysis of sintered ceramics, especially as influence on intergranular capacitor and dielectric peoperties of BaTiO3-ceramics. This fractal nature effect has been used for better understanding integrated microelectronics characteristics and circuits.
