Metal powder compacts can be well heated in microwave magnetic field, however they cannot be heated well anymore if sintering progresses and become dense, because they become a bulk body and microwave cannot penetrate into the internal area. On the other hand, microwave penetration depth into lossy ceramic materials is not large enough and the volumetric heating is not necessarily easy, either.
The authors have studied the composite bodies composed of metal particles and low loss ceramics for attaining the rapid and volumetric heating. Measurement of physical properties of the composites such as the effective permittivity and effective conductivity was conducted and compared with their heating characteristics by microwave. In this paper, it is intended to compare and summarize the physical property – heating rate relationships of several materials’ systems.
