Апстракт:
The fractal model of grains’ distribution in electronics ceramics bulk is a known fact. Even if the ceramics grains’ surface fractality is nonobserved in the first moment, the distribution of their contacts still bears majority of fractal characteristics. Using the Minkowski-Hlawka theorem of spherical contacts space distribution, the model of micro-capacitors distribution is formulated. The intergrain capacity storage amount depends on the Riemann Zeta function value, fractal dimension of three-dimensional graph of contact points, corrected dielectric constant (depends on specific specimen fractal morphology) and temperature, which also involves a fractal correction parameter that emerges from the Curie-Weis law. In this manner, the resulting integral capacity of electronics ceramics to absorb certain amount of energy is determined by two main factors: The geometry of intergranular configuration and the physico-chemical properties of consolidated sintered ceramics. Both components can be influenced by adjusting consolidation procedure and parameters. The master problem here is to get maximum of storage capacity with minimal energy investments in technological process. Energy storage super-micro capacitors new frontiers also open a quite new perspective in precise controling of these capacitors topology in higher electronic integration level within the fractal microelectronic.
