摘　　要：提出微波加热和微波等离子加热分步烧结方法（SSMP）．在这一方法中，把微波加热和微波等离子加热有机地结合到一个微波应用器内，等离子的激励无需在负压下进行；烧结分两步完成，先用微波直接将烧结件加热到一定温度，再用微波等离子体继续加热到烧结温度该方法既保持了微波加热烧结和微波等离子烧结的优点，又克服了这两种方法各自的缺点，原则上适用于所有陶瓷材料的微波烧结。The step sintering of microwave heating and microwave plasma heating (SSMP)was proposed in this paper. ln this process, microwave heating and plasma heating were ingeniously combined in one chamber, and vacuum was unnecessary for microwave induced pIasma. Sintering included twO steps. ln the first step, the microwave energy will directfy heat ceramics to a given temperature, above which microwave wifl mainly ionize the gas and sustain a plasma. Then the plasma will heat ceramics to the final temperature to finish sintering. Maintaining the advantages of microwave heating and plasma heating, this step approach will overcome the limitation of both processes for processing ceramics. Therefore, it can be used to sinter all ceramics in principle.
