1.Introduction    

The spark plasma sintering furnace (SPS) is the latest high speed metal sintering furnace. 

This kind of vacuum sintering furnace is highly characterized by astonishing sintering speed and superior output compactness.Our atmosphere sintering furnace is the industry proven solution  to sintering of nanophase materials, functionally graded material (FGM), nanoscale thermoelectric 

materials, rare earth permanent magnets, target materials and medical implants, etc.
