Tungsten Carbide Nozzle Microwave Sintering Technology II

Compared to traditional sintering process, microwave sintering technology increases the kinetic energy of interior sintered material molecules, atoms, ions, etc. And the sintered material reduced activation energy, increased diffusion coefficient, which can be fast sintering and getting grain refinement through the interaction of microwave sintering material at low-temperature. Microwave radiation can promote densification specifically due to it is not only heating energy, but also a sintering activation process. To analyze the phenomenon, the structure and the apparent activation energy, microwave radiation was found indeed largely contributed to the diffusion of atoms, and the diffusion coefficient under microwave heating was significantly higher than the diffusion coefficient under conventional heating.
