Nano-structuring in systems of thermal-synthesis hardening in the form of two interconnected technological stages is presented: the nano-technology of the synthesis of initial precur- sors (powders) with realization of the “bottom-up” principle, and the technology of nano-structuring of thermal-synthesis systems with the acquisition of solid state under the thermal impact realized by the “up-down” principle. Considered nano-ceramic compositions on the basis of zirconium dioxide, obtained with due regard for these two technologies, have high strength characteristics: values of micro-hardness (in the range of 70–170 kPA), crack resistance (over 25 MPa/m2 and compression strength (700–900 MPa) that is connected with the nature of a component introduced (In2O3) and its optimal quantity in the composition of ceramic composition. It is established that an evolution model of acquiring the solid state pro- posed for thermal-synthesis systems of hardening can be used for simulating similar processes of the nano-structuring in the ceramics.
