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 i...n thin films and nano technologies as well.
