METHOD FOR PRODUCING THE MATERIAL OF AN ION TRANSPORT MEMBRANE Russian patent published in 2022 - IPC B01D61/00 B01D71/02 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for producing the material of an ion-transport membrane, including solid-phase synthesis of Bi_1,6Er_0,4O₃ for 20 hours at 800°C from Bi₂O₃ and Er₂O₃ oxides, synthesis of Ag₂O by deposition from an aqueous solution of silver nitrate, and hot pressing of the charge of Bi_1,6Er_0,4O₃, Ag₂O and metal indium in an argon medium, followed by firing in an argon furnace, characterised by the fact that the material has the composition Bi_1,6Er_0,4O₃ - 27 wt.%, Ag - 3 wt.%., In. Hot pressing is performed at 750°C and at a pressure of 8 MPa for 3 hours followed by firing in a furnace at 700 to 750°C for 24 hours.

EFFECT: production of the material of an ion-transport membrane.
