TITANIUM LIGATURE FOR ALLOYS BASED ON Ti-Al Russian patent published in 2021 - IPC C25C3/36 C25C5/04 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to options of a method for electrolytical recycling of titanium aluminides to obtain Ti-Al ligatures. The method for electrolytical recycling of titanium aluminides to obtain Ti-Al ligatures includes the placement of titanium aluminide containing more than 10 wt.% of aluminum and at least 10 wt.% of oxygen to a reactor equipped with an anode, a cathode and an electrolyte containing halogen salts of alkaline metals or alkaline earth metals or a combination thereof, heating of the electrolyte to a temperature of 500-900°C, sufficient to create a mixture of a molten electrolyte, passage of electric current from the anode through the mixture of the molten electrolyte to the cathode, and dissolution of titanium aluminide from the anode to deposit Ti-Al ligature on the cathode, including up to 5 wt.% of aluminum.

EFFECT: obtaining Ti-Al ligature from titanium aluminides is provided without the addition of titanium chlorides or other forms of soluble titanium to the electrolyte, containing halogen salts of alkaline metals or alkaline earth metals or a combination thereof.
