Abstract Al2O3-MgO and Al2O3:ZrO2-SiO2 mixtures were reaction sintered in a single mode cylindrical cavity applicator CMPR-250 operating at 2.45 GHz in the TM012 mode to form spinel MgAl2O4 and ZrO2 dispersed mullite matrix composites respectively. High heating rates at low power levels were achieved. Consequently, fine grain size and high density were achieved. High purity submicron unreacted powders were sintered from an initial green density of 60% to a final sintered density close to the theoretical density.
