S3 Spark Plasma Sintering Furnace

The spark plasma sintering system is one of the most advanced sintering systems in the world today. It is a new type of rapid sintering technology that applies pulse current and axial pressure between two electrodes for powder sintering densification. It has the distinctive characteristics of fast heating rate, short sintering time, controllable structure, energy saving and environmental protection. It can be used to prepare metal materials, ceramic materials, composite materials, nano block materials, amorphous block materials, gradient materials.
