The present work reports electrochemical synthesis of MgB 6 from molten salts using the precursor consists of LiF–B 2 O 3 –MgCl 2 . An attempt has been made to synthesize metastable phase MgB 6 crystal by electrolysis method. DTA/TGA studies were made to determine the eutectic point of the melt and it was found to be around 900°C. The electrolysis was performed at 900°C under argon atmosphere, at current density of 1.5 A/cm 2 . The electrodeposited crystals were examined using XRD, SEM, and XPS. From the above studies, the electrochemical synthesis method for hypothetical MgB 6 from chloro-oxy-fluoride molten salt system is provided. Mechanism for the formation of magnesium hexaboride is discussed.
