AB  - Metal-endings are integral part of different ultrasonic sandwich transducers. In this paper a new Matlab/Simulink 3D model of of the finite metal rings and discs of various dimensions is realized. With this model, which describes both the thickness and the radial resonant modes, and the coupling between them, mechanical impedance of the sample can be easily computed. Resonance frequency-length curves for rings and disks with various materials and for different selected dimensions are given. Also, comparisons of the different approaches in determining of their resonant frequencies are shown. The proposed Matlab/Simulink model requires simpler implementation than other analytical models. That enabled modifying of 1D theory and simplified modelling and projecting of the ultrasonic sandwich transducers with short-endings. Finally, the computed and experimental results are compared.

AB  - Taking into account that microstructure properties of barium-titanate based materials, expressed in grain boundary contacts, are of basic importance for electric properties of these material, in this study, the model of intergranular impedance is established using the equivalent electrical scheme characterized by corresponding frequency characteristic. Globally, BaTiO3 sample is consisted of a huge number of mutually contacted grains which form clusters. For each of them, it is possible to establish the equivalent electrical model and, for defined set of input parameters, using symbolic analysis, obtain the frequency diagram. Realizing the totality of relations betwecn clusters grains groups, their microelectrical schemes and corresponding frequency characteristics, from one side, and global equivalent electrical scheme and corresponding acquired frequency characteristics of BaTiO3 samples, on the other side, we set a goal of coinciding experimental results with the summing effect of microclectric equivalent schemes. The model is successfully tested on barium titanate ceramics doped with Er2O3Yb 2O3.

AB  - Doped barium-titanate ceramic is attracting much interest for its application as resistors with a positive temperature coefficient of resistivity (PTCR), multilayer ceramic capacitors (MLCC), thermal sensors etc. In this article the influence of Yb2O3, Er2O 3 and Ho2O3 on microstructure development and dielectric properties of BaTiO3 ceramics has been presented. BaTiO3-ceramics doped with 0.5 up to 1 wt % of Yb2O 3, Er2O3 and Ho2O3 were prepared by conventional solid state procedure and sintered up to 1320°C for two hours. Microstructure investigations of doped BaTiO3 was performed using the scanning electron microscopy (SEM), energy dispersive spectrometer (EDS) and stereological methods. The measurements of capacitance and dielectric losses as a function of frequency and temperature were evaluated by matching model. Special attention has been focused on the study of the changes in morphology, grain and pore size distribution of the sintered specimens and their correlation with the change of capacity, dielectric permittivity and Curie temperature.
