Abstract

There is required titanium disulfide of high purity and stoichiometric composition as electrode material for certain types of batteries. With the known process for reacting preheated gaseous titanium tetrachloride with an excess of preheated gaseous hydrogen sulfide at 400.degree. to 600.degree. C., there is obtained a product which is not optimally usable. A titanium disulfide quality of higher purity and stoichiometry is obtained by forcing a deposition of the titanium disulfide on the inner walls of the reactor through regulating the temperature at the reactor walls and/or the residence time of the gaseous mixture. The titanium disulfide can be mechanically stripped off the walls and removed countercurrently to the waste gas stream from the reactor.
