通过求解烧结后期晶粒生长和孔隙率方程（Svoboda 和 Riedel 1992），并结合热传导方程和电场，对陶瓷材料的微波加热进行了分析！ I-D 板的方程。在没有烧结的情况下，计算了 Al2O3 和 SiC 的微波功率吸收和加热曲线，并进行了计算以研究 Al2O3 介电损耗随温度增加的影响。微波和传统烧结过程中 Al2O3 致密化和晶粒生长的比较表明，在本模型的框架内，两种加热模式在烧结后期没有差异。
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 I-D slabs. Microwave power absorption and heating profiles have been calculated for Al2O3 and SiC in the absence of sintering and calculations have been carried out to study the effect of increasing dielectric loss of Al2O3 as a function of temperature. A comparison of the densification and grain growth for Al2O3 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.
