In the present study the multifunctional composite materials on zirconia based for different applications were synthesized, studied and analyzed. It has been shown that the using of liquid solutions reagents instead of powders mixing allows entering in the matrix material the oxide dopants in supersaturated concentrations. The nanoparticles synthesized during this investigation contain a potential for the formation of various structures. By the controlling of heating regimes during nanopowders firing or sintering processes it become possible to control the diffusion processes on the particles volume and boundaries. In this study was found the decomposition of initial supersaturated solid solution during heat treatment leads to formation of multilevel nanocomposite structure in the ceramic matrix with enhancing mechanical, electrical, optical and catalytic properties. It was established that the modification of zirconia even a slight amount of aluminum oxide, zinc oxide leads to a significant changing in the properties of nanopowders and ceramics.
