FIELD: chemistry.SUBSTANCE: invention can be applied in microelectronics. To obtaining complex yttrium, barium and copper oxide YBaCuO, 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.1 ex |
