Влияние микроструктуры и фазового состава на механические свойства композита ZrO[2]-MgO с бимодальной поровой структурой

Abstract

In this paper porous ceramics based on the ZrO[2]-MgO 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 ZrO[2] 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.
