In the present work the influences of thermal-baric effect in the process of nanostructured alumina and zirconia powders consolidation on structure and physical-mechanical properties of the composite ceramics have been investigated. The samples of ceramics have been prepared from nanostructured powders (ZrO2 -3 mol. % Y2O3) and Al2O3 in ratio from 100 : 0 to 20 : 80 wt. % in two ways: by static uniaxial pressing and by pulse pressing. Then part blanks were annealed in the temperature region 1560-1670 oC. During pulse process a crystal structure of samples was disordered, and monoclinic ZrO2 lattice was partially deformed. After a heat treatment of a blank the crystal structure of metal oxides was restored. Ceramics of oxide powders with content 100 - 50 wt. % PSZ synthesized at the 1100 oС possessed a higher level of properties than one of active powders prepared at the 900 oC.
