It features a: Microwave and direct coupling material, resulting in an overall heating
　
Due to the volume of microwave heating, to achieve zero gradient material large area uniform heating, so that the internal thermal stress reduced, thereby reducing cracking and deformation tendency. And because the microwave can be absorbed by the material directly into heat, therefore, high energy efficiency, energy efficient than conventional sintering about 80%.
　
Features 2: microwave sintering heating speed, the sintering time is short
　
Some materials in the temperature above the critical temperature, which rapidly increases the loss factor, resulting in fast heating. In addition, there is a decrease in the activation energy microwave to speed up the process of the sintered material, sintering time shortens. Short sintered grain is not easy to grow up, and easy to obtain a homogeneous fine grain microstructure, less internal porosity, void shape than conventional sintering round, which has better ductility and toughness. At the same time, the sintering temperature is also significantly lower.
　
Features 3: Microwave can selectively heating phase
　
Due to different materials, different microwave absorbing material relative differences, it is possible to obtain new materials and new structures and by selectively heating or selective chemical reactions. You can also add absorbing phase to control the heating area, high-absorbency material may also be used to preheat the microwave transparent material, the use of hybrid heating sintering low loss material. In addition, the microwave sintering is easy to control, safe, pollution-free.
