In the case of argon-chloric plasma ( Ar ; 10 L/min , Cl 2 ; 0.25 L/min ), Fe selectively evaporates.
And, in the case of argon-chlorine-oxygen plasma, if the flux of oxygen is small, Fe selectively evaporates.
Meanwhile, if the flux of oxygen increases into 1.0 or 2.5 L/min , the evaporation of Fe is suppressed to generate oxides with low steam-pressure.
Furthermore, the concentration of Co in hume becomes higher to generate chlorides with high-pressured steam.
So, we can separate components of Fe or Co from Fe-Co-Ni alloys by chloric plasma.
