Title: | Synthesis of the high temperature superconductor YBa2Cu3O7-delta by the hydroxide co-precipitation method | Authors: | SCHILDERMANS, Inge VAN BAEL, Marlies KNAEPEN, Els YPERMAN, Jan MULLENS, Jules VAN POUCKE, Lucien |
Issue Date: | 1997 | Publisher: | ELSEVIER SCIENCE BV | Source: | PHYSICA C-SUPERCONDUCTIVITY AND ITS APPLICATIONS, 278(1-2). p. 55-61 | Abstract: | A new synthetic route is developed to prepare a hydroxide precursor for the superconductor YBa2Cu3O7-delta. In an inert atmosphere and at low temperature the yttrium, barium and copper hydroxides are co-precipitated by adding the metal perchlorates and sodium hydroxide together. The analysis of the precursor proved the absence of ClO4- and Na+ ions. The thermal treatment (12 h calcinating at 950 degrees C, 35 h sintering at 950 degrees C and 6 h annealing at 400 degrees C) gives a superconductor YBa2Cu3O7-delta with a transition temperature of 90.2 K. | Notes: | Schildermans, I, LIMBURGS UNIV CTR,LAB INORGAN & PHYS CHEM,UNIV CAMPUS,B-3590 DIEPENBEEK,BELGIUM. | Keywords: | synthesis; co-precipitation; YBa2Cu3O7-delta | Document URI: | http://hdl.handle.net/1942/3330 | DOI: | 10.1016/S0921-4534(97)00105-6 | ISI #: | A1997XB79300008 | Type: | Journal Contribution |
