The plasma state is one of the four fundamental state of matter, along with gaseous, liquid and solid states.
The plasma state forms at very high temperatures when the energy of a gas, or a mix of gases, is such that electrons can be extracted from the atoms. In such a state, the plasmas display unique properties and behaviors.
In industry, the plasma state has been recently used to heat some media to extreme high temperatures or to inlay a specific property within a material.
This is where the JEMA SA power supplies intervene.
There are several ways to achieve the plasma state. One of them is by use of a controlled Direct Current Electric Arc, which provides a lot of energy locally that can be combined with the thermodynamic expansion of a gas to achieve very high temperatures and very high velocities.
In industry, plasmas are created in a so-called torch that initates and hosts the electric arc, insures the mix of gases and the cooling of the exterior metal parts.
JEMA SA supplies the DC power systems that initiate and control the electric arc in the torch.
Reverse metallurgy is the process of recycling metals within the emerging value chain of circular economy. In this way, it is possible to recover pure metals from waste, close to its original high intrinsic value.
Residues containing metal are mechanically crushed and the metallic parts are separated as much as possible from non-metallic parts using mechanical processes. The remaining metal-rich compound is then heated by a plasma torch to very high temperatures that cause the metal to boil and evaporate.
This evaporation leaves the non-metallic parts in the furnace while the vapor condenses further in the process into pure metal that can be reused in industry.
