MgO-Al2O3 Spinel possess low mechanical property at room and high temperature . This can be improved by partial attachment of ZrO2 to the parent spinel phase. At the attachment of these ZrO2, its mechanical properties are highly increased. It was confirmed that at high temperature monoclinic form of ZrO2 was changed. The Monoclinic form of ZrO2 was changed to tetragonal or cubic form at high temperature. The general structure of MgOAl2O3 is similar to the spinel structure AB2O4 (MgAl2O4). The article reports the preparation of zirconia –spinel (composites) using sintering method and characterization of zirconia -spinel.
