Titanium(IV) chloride vapour is introduced into a stream of molten sodium, and the chloride is reduced to the metal. Titanium and sodium chloride are formed as solids, and are extracted from the sodium stream by filtering. After removing residual sodium, the titanium metal can be separated from the salt by simple washing.

Greener synthesis of chemical compounds and materials

In the synthesis of metal sulfides, the hydrothermal synthesis is short (up to 4 h) and it can be used at low temperatures (150°C) without pH control and complexing agents, resulting in pure final products with high yield (greater than 93%). Thus, obtained metal sulfides are potential candidates for deeper study of water-splitting processes.
