Modeling Microwave Heating of Ceramics

Abstract

A method to simulate microwave heating of ceramics which has a temperature dependent dielectric property is developed here. In this simulation study, the impedance method is used to find the microwave energy absorbed by ceramics and a non-linear finite element method is used to determine the dynamic temperature profile in the ceramics during microwave heating. Using the developed method, the thermal runaway phenomenon in the microwave heating of ceramics is successfully simulated. With detailed analysis of the microwave energy absorption pattern in the ceramics, the effects of dielectric properties on microwave energy absorption by ceramics are discussed. The causes of non- uniform heating with microwave energy that has been observed in our laboratory are also investigated.
