AB  - A new correlation between microstructure and doped BaTiOrceramics properties is developed based on fractal geometry. The BaTiO3-based materials structure can be controlled by using different sintering temperatures and additive concentrations. In this paper, Ho2O3-doped BaTi03-ceramics microstructure properties have been investigated. The dopant concentration ratio is from 0.01 to 1 wt% of Ho2O3• The sintering has been done by using three different temperatures (1320, 1350, and 1380 °C). BaTi03 microstructure and compositional studies were investigated by SEM (scanning electron microscope) equipped with EDS analysis. By using the fractal objects theory, the reconstruction of microstructure configurations such as grains contour shapes and the nature of intergranular contacts has been approximately established. Using fractal tools in studying BaTiO3 ceramics microstructure has a great significance for future components technology developments, materials function integrations, and miniaturization. The complementary statistical approach contributes to the investigation of BaTiO3 ceramic grains distribution and nature of intergrain contacts, which brings a major shift in the field of electronic components and alternative energy sources.

AB  - With increasing of the world energy crisis, research for new, renewable and alternative energy sources are in growth. The focus is on research areas, sometimes of minor importance and applications, where the different synthesis methods and microstructure properties optimization, performed significant improvement of output materials’ and components’ electro-physical properties, which is important for higher energy efficiency and in the electricity production (batteries and battery systems, fuel cells and hydrogen energy) contribution. Also, the storage tanks capacity improvement, for the energy produced on such way, which is one of the most important development issues in the energy sphere, represents a very promising research and application area. Having in mind, the results achieved in the electrochemical energy sources field, especially electrolyte development, these energy sources, materials fractal nature optimization analysis contribution, have been investigated. Based on materials fractal structure research field, particularly electronic materials, we have performed microstructure influence parameters research in electrochemistry area. We have investigated the Ho2O3concentration influence (from 0.01wt% to 1wt%) and sintering temperature (from 1320°C to 1380°C), as consolidation parameters, and thus, also open the electrochemical function fractalization door and in the basic thermodynamic parameters the fractal correction introduced.

AB  - Ceramics grain structure is difficult to describe by using traditional analytical methods based on Euclidean geometry. Using the fractal geometric/analytic methods instead, the new approach is offered in this paper. There are a many materials that can be doped to BaTiO3, in order to gain different characteristics and in this study we are using Ho2O3. Different concentrations has been used, as well as different sintering temperatures. For selected contacted grains, the SEM (Scanning Electron Microscope) pictures are taken providing suitable configuration for an electrical model study. It is shown that ferroelectric, optoelectric and piezoelectric properties, are influenced by fractal structure of grains and intergrains contacts, distribution of pores and inner dynamics during sintering process. Nowadays the material science is aware of importance of taking fractal properties of different ceramics and a new analytic and numerical models are suggested. The similar behavior is discovered in thin films and nano technologies as well.

AB  - An influence of dopant concentration on microstructure and dielectric properties of doped BaTiO3-ceramics is developed based on fractal geometry. Using different technological parameters and different additives the structure of BaTiO3 based ceramics materials can be controlled. In this research, BaTiO3 samples with different concentration of Ho2O3 are used. The ratio of dopant concentration ranges from 0.05% to 1%. The sintering temperature of 1350°C is chosen. Selected specimens of BaTiO3 were documented using SEM (Scanning Electron Microscope) equipped with EDS analysis. As it is expected, the influence of impurities on intergranular capacity and other electrical properties is significant which is demonstrated and confirmed in this paper. Using the method of fractal modeling, a reconstruction of microstructure configurations, like grains shapes or intergranular contacts is performed. Such interdisciplinary research is important for opening new frontiers in electronics, and give us a fine perspective in dielectric materials. A merit of such perspective is definition of a bond between microelectronics and materials and components made for sensors and actuators.
