As a time-saving, energy-saving, labor-saving and pollution-free technology, microwave sintering can meet the requirements of energy conservation and environmental protection. Its activated sintering characteristics are conducive to obtaining excellent microstructures, thus improving material properties. The characteristics of microwave-material coupling determine that microwave can be used for principled heating, thus making it possible to produce special microstructures. Materials, such as functionally gradient materials. In the traditional sintering process, when the compactness of the specimen is high, the propagation rate of combustion wave caused by the traditional heating method decreases greatly, and even can not spontaneously ignite because of "self-extinguishing". However, if microwave irradiation is used, because the temperature rise is the result of microwave energy absorbed by the reactant itself, as long as the microwave continuously gives energy, the sample temperature will soon reach the ignition temperature. Once the reaction is initiated, the heat released will further increase the temperature of the sample to the combustion temperature, and the ability of the sample to absorb microwave radiation will also increase, which ensures that the reaction can be maintained at a sufficiently high temperature until the reaction is complete. Microwave combustion synthesis or microwave sintering is a controllable process. That is to say, we can control the propagation of combustion wave artificially by adjusting a series of parameters according to the requirements of product properties. This is a remarkable advantage of microwave combustion synthesis over traditional technology. The microwave power can be adjusted by directly using a microwave source with adjustable power to control the absorption of microwave energy by the sample. With the development of microwave sintering equipment towards higher power density, automation and intelligence, microwave sintering technology will become the most promising new generation of sintering technology.
