METHOD OF OBTAINING COMPLEX YTTRIUM, BARIUM AND COPPER OXIDE Russian patent published in 2014 - IPC C01F17/00 C01F11/00 C01G3/00 

FIELD: chemistry.

SUBSTANCE: invention can be applied in microelectronics. To obtaining complex yttrium, barium and copper oxide YBa₂Cu₃O_7-δ, from water solution, which contains yttrium, barium and copper nitrates, combined sorption of yttrium, barium, copper in given molar ratio Y:Ba:Cu = 1:2:3 is carried out at the stage of sorption from the said solution on carboxyl cationite KB-4p-2. After that, obtained material is dried and subjected to successive heating at temperature 110 - for 2 h, at 250°C - for 2 h, at 450°C - for 5 h, at 600°C - for 3 h, at 850°C - for 6 h and after that for 1 hour in oxygen atmosphere.

EFFECT: invention makes it possible to simplify obtaining complex yttrium, barium and copper oxide.
