Microwave sintering is a sintering process in which objective materials absorb microwave and heat themselves from the inside. When microwave energy is effectively absorbed to the material, energy consumption for the sintering can be reduced. In this work, a domestic microwave oven was employed for sintering ceramics. However, it is difficult to absorb them effectively for the long wave. Then, the method of efficiently absorbing the microwave is needed. In general, dielectric loss of ceramics is low at room temperature, but it is high at high temperature. The material which dielectric loss is high at room temperature was used as a susceptor. we were investigated include optimization of heating system set up, determination of maximal densification level, influence of SiC susceptor on temperature distribution, comparison of microwave and conventionally sintered specimens regarding their density. They were examined by using the ZnO as a model material.
