First, thermodynamic estimation of the possibility of electrochemical synthesis of TiB 2 from cryolite-alumina melts containing oxides of titanium and boron has been carried out. Then, the possibility of synthesis of TiB 2 was studied by linear voltammetric measurements with 0.01–0.1 V/s scan rates at 1273 K. Finally, electrolysis experiments were performed on cathodes made of graphite, Mo, and Nb in graphite crucibles, from Na 3 AlF 6 -Al 2 O 3 -TiO 2 -B 2 O 3 melt, at 1273 K. Eventually it was concluded that TiB 2 layers can be deposited from cryolite-alumina melts containing oxides of titanium and boron under certain circumstances.
