This research prospect focuses on the investigation of the effect and changes in the material properties like density, porosity, grain size, microhardness, and microstructure on addition of MgO (0.5% vol., 1% vol., and 2% vol.) and 10% vol. of zirconia (ZrO2) in the matrix of alumina. Here, magnesia-zirconia-toughened microwave-sintered alumina nanocomposite samples were prepared successfully and suppression of grain growth as well as crack-free microstructure development was achieved. No damage of material was found due to thermal shocks for up to 1500°C of processing temperature. Further, the rapid heating process was executed at 25°C/min rate under non-pressurized conditions. Sintering temperature and holding time were taken as 1500°C and 60 min, respectively. Moreover, uniform microstructure was detected using the field emission scanning electron microscopy (FE-SEM) techniques. Level of submicron-sized grain was obtained for the nanocomposite material’s microstructure without any significant increase in the grain size. Properties such as density, porosity, hardness, and microstructure of alumina nanocomposite were enhanced because of suppressed grain growth. The fabricated composite is suitable for ballistic armor and thermal barrier coating purpose.
