The microwave heating of ceramic materials has been analyzed by solving the equations for grain growth and porosity (Svoboda and Riedel, 1992) during the late stages of sintering, coupled with the heat conduction equation and electric field equations for 1-D slabs. Microwave power absorption and heating profiles have been calculated for $Al_2O_3$ and Sic in the absence of sintering, and calculations have been cam'ed out to study the effect of increasing dielectric loss of $Al_2O_3$ as a function of temperature. A comparison of the densification and grain growth for $Al_2O_3$ during microwave and conventional sintering indicates that within the framework of the present model, there is no difference between the two heating modes during the late stages of sintering.
