Peculiar reactions are known to occur using the features of arc plasmas, high temperature and high chemical activity, according to circumstances that are very effective. However few chemical reactions of arc plasmas have been unknown. Researches in the field of arc plasma reactions have been used hydrogen plasma gas to reduce metal oxides and to add heat to samples excessively, but there are very few thermodynamic data on hydrides which cause the plasma reactions. We have investigated the arc plasma reactions with chlorine because it reacts with metal to form chlorides which have high vapor pressure to be separated peculiarly and there are many available thermodynamic data on chlorides to study the reaction mechanism theoretically, and succeeded in separating iron component from Fe-Co-Ni alloys.
