Формирование и исследование свойств композитов ZrO[2](Mg)-MgO

Abstract

These studies shows which structures and properties have composites based on ZrO[2](Mg)-MgO sintered in a wide temperature range from 1400to 1650{о}С. X-ray diffraction showed an increasing of crystalline size with increasing of magnesia concentration. Decreasing of sintering temperature accompanied with an increasing of porosity and reduction of the compressive strength. Scanning electron microscopy showed the morphology of the composite structure. It is discovered that the pore size in the zirconia matrix in an order of magnitude higher than in magnesia inclusions.
