AB  - Sintering process is a complex of different synergetic effects during the ceramics materials consolidation. The microstructural level properties control is very important as a stage in advanced materials prognosis. SEM analysis of Yb/BaTiO3 doped ceramics showed that in samples doped with, a low level of dopant and sintered at higher temperatures the grain size ranged from 10-60 mu m, while with the higher dopant concentration the grain, size ranged between 2-15 mu m. The morphology of sintered BaTiO3-ceramics grains points out the validity of developing new structure analytical methods based on different geometries of grains' model systems. The idea of electrical properties of BaTiO3-ceramics being influenced by intergrain microcontacts can be successfully followed if we start with the two-sphere Coble's model and also the correction of the Coble's model. In this paper, the grains contact models based on spherical, ellipsoidal and polyhedral geometries are presented making a new modeling tool for structure research of BaTiO3-ceramics materials. Intergranular impedance analysis of grains clusters was also introduced. Obtained results enabled establishment of interrelation between. structural and electrical parameters.

AB  - BaTiO3-ceramics are known as some of the most useful electroceramics with a various applications. In this study the effect of Er2O3 as additive on the microstructure and dielectric properties of doped BaTiO3 was investigated. The samples doped with 0.01 to 1.0 wt% Er2O3 were prepared using by conventional solid state procedure, and were sintered at 1350 degrees C for four hours. The microstructure of sintered specimens was investigated by SEM-5300 and capacitance and dielectric loss measurements have been done using LCR-metra Agilent 4284A in the frequency range from 20Hz to 1MHz. The microstructure study with low additive concentration shows abnormal grain size, with average grain size between 20-60 mu m. With the higher dopant concentracion the abnormal grain growth is inhibited and the grain size ranged between 5-15 mu m. The dielectric constant decrease with increase of dopant concentration and for all of the investigated samples ranged from 650 to 1600 at room temperature. The dissipation losses a linear decrease v.s frequency is mesured for all investigated samples. We applied a fractal method for the microstructure analysis. This method for analysis of the structure of ceramics provides a new approach for describing, predicting and modeling the grain shape and relations between the BaTiO3 ceramic structure and dielectrical properties.

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-ceramics 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 between 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-ceramics samples, on the other side, we set a goal of coinciding experimental results with the summing effect of microelectric equivalent schemes. The model is successfully tested on barium titanate ceramics doped with Er2O3, Yb2O3.

AB  - In this article the additives Yb and Er oxides are used as doping materials for BaTiO3-based multilayer devices. 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 up to 0.5 wt % of Yb2O3 and Er2O3 were prepared by conventional solid state procedure and sintered up to 1320 degrees C for four hours. In BaTiO3 doped with a low level of rare-earth ions the grain size ranged from 10-60 mu m. With the higher dopant concentration the abnormal grain growth is inhibited and the grain size ranged from between 2-10 mu m. The measurements of capacitance and dielectric losses as a function of frequency and temperature have been done in order to correlate the microstructure and dielectric properties of doped BaTiO3-ceramics. The temperature dependence of the dielectric constant as a function of dopant amount has been investigated.

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.

AB  - Ceramic materials with a perovskite related structures such as non-doped and doped barium titanate ceramics are attracting much interest for their application as capacitor dielectrics, resistors, thermal sensors, etc. Since mechanical activation can be used in order to modify properties of these materials, in this study microstructure evolution and electric properties of mechanically activated BaTiO3 have been analyzed. The sintering process of high purity non-doped mechanically activated BaTiO3 was monitored using a sensitive dilatometer with a heating rate of 10 degrees C/min. Investigation of the microstructure evolution of mechanically activated BaTiO3 was performed using scanning electron microscope (SEM) and digital pattern recognition (DPR) methods. A dielectric study of the paraelectric-ferroelectric phase transition in the barium titanate ceramics was performed by recording the temperature dependence of dielectric permittivity.

AB  - In this paper the influence of tribophysical activation on non-isothermal sintering of barium titanate has been investigated. BaTiO3 Powders were tribophysically activated in a planetary ball mill for 0, 60 and 120 min., pressed and non-isothermally sintered up to 1380 degrees C. Dilatometric analysis was performed in air in the temperature range from room temperature to 1380 degrees C with heating rates of 10, 20 and 30 degrees C/min. The samples were analyzed by the X-ray powder diffraction method. Investigation of the morphology of microstructure constituents was performed using the scanning electron microsocopy method. With the purpose of optimizing technological parameters the results obtained by microstructure analysis were correlated with the results of quantitative dilatometric analysis.

AB  - BaTiO3 is usually doped to achieve the temperature stability required by device applications, as well as to obtain a large positive temperature coefficient anomaly of resistivity (PTCR). Uniform distribution of dopants among the submicron dielectric particles is the key for optimal control of grain size and microstructure to maintain a high reliability. The system Ba0.84Pb0.16TiO3 was synthesized from high purity BaCO3, TiO2, PbO oxide powders as raw materials. Sb2O3, MnSO4 and ZnO were used as dopants and Al2O3, TiO2 and SiO2 as grain growth controllers. Phase composition was analyzed by using XRD and the microstructure was investigated by SEM. EDS attached to SEM was used to analyze phase composition specially related to abnormal grain growth. Electrical resistivities were measured as a function of temperature and the PTCR effect characterized by an abrupt increase on resistivity.
