in KF-1%MgF2 molten salt, and the electrochemical reduction of B3+ is also a one-step reaction as B3++3e-→B in KF-KBF4 (1%, 2% KBF4) molten salts. Both the cathodic reduction reactions of Mg2+ and B3..., the electrochemical synthesis of MgB2 by co-deposition of Mg and B was carried out in the KF-MgF2-KBF4 (molar ratio of 6:1:2) molten salt at 750 °C. The X-ray diffraction analysis indicates that MgB2......
