| titleOfInvention | METHOD FOR OBTAINING RARE-EARTH ELEMENTS AND BARIUM |
| abstract | A method for producing cuprates of rare-earth elements and barium, including calcining a heteropolynuclear complex of nitrates of rare-earth elements, copper (II), barium and pyridine, characterized in that first a preliminary firing of a heteropolynuclear complex of the composition Ln (NO3) 3 2Ва (NO3) 2 3Cu (NO3 ) 2 9 (C5H5N HNO3) nH2O at 250-300 ° C for 5-10 min with cooling to room temperature, grinding and main firing at 900-930 ° C (Ln = Tb, Dy, Ho, Er ) or 850-880 ° C (Ln = Sm, Eu, Gd). |
