The invention relates to non-ferrous metallurgy and concerns a device for chlorinating titanium-containing material in a solution of chloride salts. The technical effect of the invention is an increase in the service life of the device and a reduction in raw material losses. This technical effect is achieved by means of the proposed device for chlorinating titanium-containing material in a solution of chloride salts, comprising a housing, a lined upper cylindrical chamber for a gas-vapour mixture, a lined chlorinating chamber in the shape of an inverted truncated cone, the generatrix of which is inclined at an angle of 15-25° to the axis of the chamber, graphite electrodes, a hearth, tuyeres, chlorine feed lines, and a feedstock charging assembly, wherein the housing is provided with reinforcing ribs in the region of the chlorinating chamber and of an upper drainage pocket.

Titanium-containing film forming compositions comprising titanium halide-containing precursors are disclosed. Also disclosed are methods of synthesizing and using the disclosed precursors to deposit Titanium-containing films on one or more substrates via vapor deposition processes.

The present invention relates to the recovery of rare earths, scandium, niobium, tantalum, zirconium, hafnium, titanium, and the like from ores or concentrates containing fluorine. More specifically, the ores or concentrates are pretreated by carbochlorination to convert the rare earths and other metals into their chlorides and then subjected to dilute hydrochloric acid leaching to recover the valuable rare earths and other metals from the leachate. Niobium, tantalum, zirconium, hafnium, and titanium can be recovered as their chlorides or oxychlorides from the gaseous products of carbochlorination, or converted into their oxides while simultaneously regenerating chlorine.
