摘　　要：通过改进混合加热模式,实现了ZTA陶瓷微波烧结。材料的类型及配比直接影响微波烧结的升温速率;输入功率的提高有助于提高烧结速率;辅助加热体的老化现象降低微波烧结速率;微波烧结过程中应避免出现热剧变现象。TE444 multi-mode microwave sintering system was designed and Hybrid Heating System was developed with well arranged Aided Heaters. ZTA ceramics were fabricated at different microwave sintering temperature. Weight percentage of ZrO2 in ZTA samples affected the microwave sintering rate, which shows that the increase in output power is favourable to the raise of the sintering temperature, but the aging phenomena of Aided Heaters is otherwise , and the Thermal Runaway should be avoided during the process of microwave sintering.
