研究了不同材料在不同微波场中的微波加热行为。一个2.45 GHz，1.2千瓦的微波发生器与功率监控器被用作微波源。使用红外高温计测量金属样品的温度。通过石英管通入帕辛，避免了金属样品在高温下的氧化。磁场对碳化钨-钴（WC-Co）样品的加热效果较好，电场和磁场对氧化铝粉末复合样品的加热效果都较好，但磁场对样品的加热效果更快。
The microwave heating behavior of various materials in different microwave fields was investigated. A 2.45 GHz, 1.2 kW microwave generator with power monitor was used as a microwave source. The temperature of the metal sample was measured using an infrared pyrometer. The oxidation of metal samples at high temperature was avoided by pasing nitrogen gas through the quartz tube. The tungsten carbide-cobalt (WC-Co) sample can be efficiently heated up in the magnetic field and alumina-powdered composite sample can be heated up both in electric and magnetic fields, but the heating effect was faster in the magnetic fiels.
