Effect of microstructure and phase composition on mechanical properties of the composite ZrO2-MgO with a bimodal pore structure

In this paper porous ceramics based on the Zr02-Mg0 system were studied. It was shown, that the addition of an organic pore-forming particles make it possible to obtain a bimodal pore structure. X-ray diffraction analysis showed that with the increasing of MgO concentration, the average size of Zr02 and MgO crystallites grows up and their crystal lattice microdistortion decrease. Strength with increasing of MgO concentration is increasing and the dependence of compressive strength from microstresses was found
