Abstract
Under high-temperature conditions, the microwave sintering process is exceedingly sensitive in terms of material properties. Accordingly, the accurate measurement of temperature is infeasible when a microwave oven is utilized as the main apparatus. Therefore, a three-dimensional model built through the finite element software COMSOL Multiphysics was used to investigate the hybrid microwave sintering (HWMS) process. Numerical simulation of the entire microwave sintering process has been realized and it could reflect the actual sintering process. In this paper, the proposed numerical simulation entails four kinds of thickness of SiC rings. Specifically, three principal aspects were studied: the distribution of electric field, temperature variation and densification of powder injection molding (PIM) material. As a result, a significant “room-temperature” coupling was observed under the effect of susceptor in low dielectric-loss materials; The influence of susceptor ring thickness on temperature variation and densification of ceramic material was secured; The ultimate temperature remains steady at a certain heating time regardless of different thickness; The densification process was significant enhancement in the sintering stage.
