Discharge plasma sintering furnace

Discharge plasma sintering furnace features:

Discharge plasma sintering is a kind of new technology of rapid, low temperature, energy saving and environmental protection, which can be used to prepare metal, ceramics, nanomaterials, amorphous materials, composites, gradient materials, ceramics, cermets, intermetallics, composites Nano-materials and functional materials and so on. One of the most studied is the functional materials, which include thermoelectric materials, magnetic materials, functional graded materials, composite functional materials and nano-functional materials. Preparation of amorphous alloys, shape memory alloys, such as diamond also made an attempt, and achieved good results.

Plasma and plasma processing technology, is the use of discharge plasma sintering. Plasma is a material state at high temperature or under specific excitation, which is the fourth state of matter other than solid, liquid, and gaseous states. Plasma is an ionized gas, consisting of a large number of positively and negatively charged particles and neutral particles, and shows a quasi-neutral gas of collective behavior.

The plasma is a dissociated, high temperature conductive gas that provides a state of high reactivity. Plasma temperature 4000 ~ 109
99 ℃, the gas molecules and atoms in the highly activated state, and a high degree of plasma gas ionization, these properties make the plasma has become a very important material preparation and processing technology.

Plasma processing techniques have gained more applications such as plasma CVD, low temperature plasma PVD, and Plasma and ion beam etching. Plasma is currently used for oxide coating, plasma etching, in the preparation of high purity carbide and nitride powder also has some applications. Another potential area of ​​use for plasma is plasma generation in the sintering of ceramic materials, including heating, discharging and photoexcitation. Plasma generated by the discharge includes direct current discharge, radio frequency discharge, and microwave discharge plasma. Using a DC discharge plasma.
