摘要
A new concept of microstructural designing of polymer-free polycrystalline composite materials is offered. The concept based on controllable substitution during composite formation of separate crystallites making a polycrystal by pores, crystallites with other composition and/or structure or amorphous substances with preliminary FEM modeling of polycrystalline composite properties. A line of precursor small-scale production technologies and polycrystalline composites with unique and reproducible properties (micro- and nano-porous ferroelectric ceramics, ferroelectric ceramics/ceramics and ceramic/crystal composites etc.) have been developed and systematically studied.
