%X Based on the characteristic of microwave heating, the numerical heat-transfer model of two-dimensional stable-state heat conduction of microwave sintering for ceramics composites with heat conduction phases was built up and validated by the experiment of microwave sintering densification for SiCw/TZP ceramics. The prediction of the newly-established model is in accord with experimental results of composite ceramics such as SiCw/TZP ceramics. The influencing factors about two-dimensional stable-state temperature field distribution such as concentration and distribution of heat conduction phases, category of matrix and mode of thermal insulation are analyzed. The results indicate that matrix with high coefficient of thermal conductivity, heat conduction phases with high concentration, uniform distribution of heat conduction phases in matrix and appropriate thermal insulation equipment should be considered in the design of composite ceramics with heat conduction phases.
