Magnesium is more reactive than copper and in its presence, I think, copper does not react with Cl to form CuCl2 at room temperature. Please correct me if I am wrong. What happens at high temperature - temperature above the melting point of MgCl2 (714 C)? Will the copper in contact with MgCl2 dissolve (inert environment)?
Dear Saroj Bhatta, a SciFinder search revealed only little information about this system. There is only one reference I found (see attached). Apparently the copper metal does not dissolve, but some Mg diffuses into the copper. However, the authors used somewhat lower temperatures.
Cu+MgCl2=CuCl2+Mg

Thank you very much, Dr. Gargul. Could you please also provide me the related references for reporting purposes?
Dear All, I'm not a specialist in metallurgy, but as a chemist I think that no reaction will take place between copper metal and molten anhydrous MgCl2, at least not under inert conditions. As the more noble metal the copper should remain unchanged.
