TL;DR: In this article, active precursor powders of MgO-ZrO2 composite system were prepared in three different mole ratio by electrolytic interaction of inorganic salts in aqueous phase.
Abstract: Active precursor powders of MgO-ZrO2 composite system were prepared in three
different mole ratio by electrolytic interaction of inorganic salts in
aqueous phase. Complete hydrolysis occurred at the critical instability point
of the system at pH 9. The amorphous precursor powders exhibited very high
specific surface area. The sintered properties of the composite system are
dependent on mole ratio of MgO:ZrO2, sintering temperature and the rate of
crystallization of constituent phases. The presence of periclase grains and
cubic stabilized ZrO2 particles in the sintered body was confirmed by X-ray
diffraction analysis while scanning electron micrographs indicated that MgO
particles occupy the inter-granular positions between ZrO2 polycrystals.
