Susceptor-assisted microwave processing is a rapidly growing technology due to its superiority over the conventional processing. In contrast to the conventional heating from the surface, the microwave heating occurs volumetrically via direct interaction with the material. Correspondingly, the microwave heating rates are in general much faster than the heating rates in the conventional furnaces, where heat has to be transferred from the heat sources to the material via conduction, convection and radiation. The need for the susceptor stems from the fact that the majority of the ceramics are low lossy materials and they cannot couple well with the microwave at room temperatures. The susceptor provides an easy and non-invasive technique to exploit the rapid microwave processing even for the highly microwave transparent ceramics, such as alumina, silicon nitride, quartz, etc. This article critically evaluates the susceptor-assisted microwave sintering and solid state synthesis of ceramics which have been reported over the last two decades. A wide range of ceramics has been considered and each case has been analyzed in terms of the enhancement of the processing rates and product qualities (grain structure, material properties, etc.) compared to the conventional processing. It has been shown that the susceptor-assisted microwave processing can greatly reduce the processing time while providing an easy pathway to achieve the desired product qualities. The use of the appropriate susceptor is the key to achieve the fast, smooth, and reliable microwave processing of ceramics and this article provides the required database for the appropriate design of the susceptor based on the process requirement.

陶瓷的感受器辅助增强微波处理-综述

感受器辅助微波处理由于其优于常规处理的优越性而成为一项快速发展的技术。与从表面进行的常规加热相反，微波加热是通过与材料的直接相互作用在体积上发生的。相应地，微波加热速率通常比常规熔炉中的加热速率快得多，在常规熔炉中，热量必须通过传导，对流和辐射从热源传递到材料。对基座的需求源于以下事实：大多数陶瓷是低损耗材料，并且它们在室温下无法与微波良好耦合。基座提供了一种简便，无创的技术，即使对于高度微波透明的陶瓷（例如氧化铝，氮化硅，石英等。本文对过去二十年来已报道的感受器辅助的微波烧结和陶瓷的固态合成进行了严格的评估。与常规加工相比，已经考虑了广泛的陶瓷，并且根据加工速率和产品质量（晶粒结构，材料性能等）的提高对每种情况进行了分析。已经表明，基座辅助微波处理可以大大减少处理时间，同时提供实现所需产品质量的简便途径。使用合适的基座是实现快速，流畅，
