OBTAINING TITANIUM ALLOYS BY REDUCING TITANIUM TETRACHLORIDE Russian patent published in 2020 - IPC C22C14/00 C22B34/12 C22C1/04 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to methods of producing titanium alloys. Titanium alloy is obtained by adding TiCl₄ to the incoming mixture at temperature of the first reaction. Part of Ti⁴⁺ in TiCl₄ is reduced to Ti³⁺ to form a first reaction product. Incoming mixture contains aluminium and, possibly, AlCl₃ and/or, possibly, at least one halogenide of alloying element. After stopping the addition of TiCl₄, the first reaction product is heated under drying conditions to complete reduction of Ti⁴⁺ or to remove remaining TiCl₄ to form a first intermediate mixture. First intermediate mixture is a solution of a salt based on AlCl₃, which contains Ti³⁺, wherein Ti³⁺ in the first intermediate mixture is in form of TiCl₃ (AlCl₃)_x, where x is greater than 0–10. First intermediate mixture is heated to second reaction temperature. Part of Ti³⁺ is reduced to the second intermediate mixture, which is a solution of AlCl₃ based salt, which contains Ti²⁺. Additionally, the second intermediate mixture is heated to the temperature of the third reaction, wherein Ti²⁺ forms a titanium alloy by a disproportionation reaction.

EFFECT: invention enables to obtain titanium alloy materials by improved processing techniques of the titanium tetrachloride reduction reaction in AlCl₃ based reaction media.
