【Abstract】 ne of the important aspects of the research works on microwave processing of ceramics is to develop an advanced microwave heating system with optimum performance. The principle and design features of the singlemode TE103 cavity used for microwave processing of ceramics is studied. Also, its properties are tested. By adjusting a short circuit and a sliding coupling iris, the quality factor of the empty cavity reaches as high as 4200, and the voltage standingwave ratio (VSWR) is approximate to 1.02 under loaded. As the electric field intensity is very high, the system can heat ceramics rapidly. Ceramics, such as ZTA, Si3N4, Al2O3, have been sintered or joined successfully. The system is applicable for sintering or joining of smallscale ceramic samples with different dielectric properties.更多还原
