Microwave-assisted processes have recognized advantages over more conventional heating techniques. However, the effects on the materials' microstructure are still a matter of study, due to the complexity of the interaction between microwaves and matter, especially at high temperatures. Recently developed advanced microwave instrumentation allows the study of high temperature microwave heating processes in a way that was not possible before. In this paper, different materials and thermal processes induced by microwaves have been studied through the characterization of their dielectric properties with temperature. This knowledge is crucial in several aspects: to analyze the effects of the microwave field on the reaction pathways; to design and optimize microwave-assisted processes, and to predict the behavior of materials leading to repeatable and reliable heating processes, .
微波辅助工艺相对于传统加热技术具有公认的优势。然而，由于微波与物质之间相互作用的复杂性，尤其是在高温下，其对材料微观结构的影响仍是一个研究课题。最近开发的先进微波仪器使人们能够以前所未有的方式研究高温微波加热过程。在本文中，通过对不同材料随温度变化的介电特性进行表征，研究了微波诱导的不同材料和热过程。这些知识在多个方面至关重要：分析微波场对反应路径的影响；设计和优化微波辅助工艺；预测材料的行为以实现可重复且可靠的加热过程。
