The driving force for densification is provided by an electric current directly through the granular material using the pressure sintering method of direct current pulse current.In the sintering system, the heating rate and sintering temperature are controlled by adjusting the current size, so that the high-energy pulse is concentrated at the grain junction, so that the material can achieve low temperature, fast and efficient sintering.

The characteristics

It integrates plasma activation resistance heating and hot pressing, fast heating rate, short sintering time, uniform grain cooling, rapid external pressure, high density of materials, controllable sintering atmosphere, etc., but its sintering body is simple in shape and small in size, high in production cost and easy to produce pollution.
