Fast heating:
Mircowave traveling with the speed of light couples with heating material and transfers microwave energy to internal energy of material,reducing heat transfer time greatly compared with conventional heating, which reduces heat loss and saves energy.Instantaneous adjustment during control process has a good controllability of reaction and sintering without thermal inertia of conventional heating. 

Uniform heating:
Microwave heats through materials gradientlessly, entirely,synchronously and uniformly, which makes materails organization uniform and inhibits deforming and cracking during heating process.

Grain refinement:
With microwave’ s concentrated heating on materials, materials get a rapid temperature rising speed and uniform heating, which reduces holding time, lowers sintering temperature, refines grain and improves material sintering density during sintering process.
