Abstract:

Microwave heating technology has been widely used in many fields, such as chemical strengthening, metal smelting, ceramic sintering, food processing and so on, because of its advantages of green environmental protection, volume heating and selective heating. However, there are many problems in microwave reactor, such as poor transmission effect and low utilization rate of microwave. With the continuous development of microwave heating technology, more and more attention has been paid to the selection of wave-transmitting materials in microwave heating equipment. This research mainly reviewes the application status of wave-transmitting materials in the field of microwave heating. The types of wave-transmitting materials are briefly introduced, and the microwave heating containers and thermal insulation materials are discussed. The research progress of high-temperature wave-transmitting materials such as oxides, nitrides, silicates and phosphates, and medium and low-temperature wave-transmitting materials such as polytetrafluoroethylene, glass fiber reinforced resin base and epoxy resin are introduced in detail. It also specifically discusses the dielectric properties and wave-transmitting properties of various ceramic fiber products such as fiber cotton, fiber blankets and fiberboards commonly used in microwave heating. Finally, this article points out the current common problems of wave-transmitting materials for microwave heating, and prospected the application and development of wave-transmitting materials.

Key words: microwave heating, ware-transmitting material, container, insulation refractory
