Direct Synthesis of Ti-Al Compound Powders by Electrolysis in Molten LiCl-KCl

The deposition potential difference between Ti and Al is only 70 mV. The deposition reaction of Ti-Al compound happens at the potentials slightly higher than that of metallic Ti and Al. Through galvanostatic electrolysis of mixture solution of Al and Ti ions, all kinds of titanium aluminides can be directly synthesized. The composition of the product compound can be selected through adjusting the combination of Ti and Al ions in the electrolyte.
