AB  - In this study, in order to establish grain shapes of sintered ceramics, new approach on correlation between microstructure and doped BaTiO3 -ceramics properties based, on Voronoi model and mathematical statistics calculations on fractal geometry, has been developed. BaTiO3-ceramics doped with Yb2O3 (from 0.1 to 1.0wt% of Yb) were prepared by using conventional solid state procedure and were sintered from 1320 degrees C to 1380 degrees C for four hours. The microstructure of sintered specimens was investigated by Scanning electron microscope JEOL-SEM-5300. For better and deeper characterization and understanding of the ceramics material microstructure, the methods which include the fractal nature structure, and also Voronoi model and mathematical statistics calculations, are applied. In our research the Voronoi is one specific interface between fractal structure nature and different stochastically contact surfaces, defined by statistical mathematical methods. Also, the Voronoi model practically provided possibility to control the ceramics microstructure fractal nature. Mathematical statistic methods enabled establishing the real model for the prognosis based on correlation: synthesis-structures-properties.

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.
