The BaTiO3 ceramics applications based on electronic properties have very high gradient
scientific and industrial-technological interests. Our scientific research has been based on nano BaTiO3
modified with Yttrium based organometallic salt (MOD-Y). The samples have been consolidated
at a sintering temperature of 1350 C. Within the study, the new frontiers for di erent electronic
properties between the layers of BaTiO3 grains have been introduced. The research target was
grain boundary investigations and the influence on dielectric properties. After scanning electron
microscopy and dielectric measurements, it has been established that modified BaTiO3 samples with
larger grains showed a better compact state that led to a higher dielectric constant value. DC bias
stability was also investigated and showed a connection between the grain size and capacitance
stability. Analyses of functions that could approximate experimental curves were successfully
employed. Practical applicat...ion of fractal corrections was performed, based on surface ( s) and
pore size ( p) corrections, which resulted in obtainment of the relation between the capacitance and
Curie temperature. Successful introduction of fractal corrections for capacitance-Curie temperature
dependence for a set of experimental data is an important step towards further miniaturization of
intergranular capacitors.
