Powders and thin-layers of a hexagonal titanium disulfide phase have been successfully prepared by modifying the sol-gel process. The reaction of titanium isopropoxide with hydrogen sulfide causes the precipitation of a precursor which was converted to the disulfide on heat-treatment in $H_2S$ at various temperatures depending on the solvent adopted, whereas that of titanium 2-methoxyethoxide with $H_2S$ produces a stable solution which was spin-casted onto silicon substrates followed by thermolysis to give thin films. Upon heat-treatment in $H_2S$, the disulfides show interesting morphological variations in the form of their powders and thin films, which were characterized by SEM and X-ray diffractometer.
