Title: | Thermal treatment of a modified alkoxide gel precursor for the preparation of the YBa2Cu4O8 superconductor | Authors: | VAN BAEL, Marlies MULLENS, Jules NOUWEN, Ria YPERMAN, Jan VAN POUCKE, Marcel |
Issue Date: | 1997 | Publisher: | JOHN WILEY & SONS LTD | Source: | JOURNAL OF THERMAL ANALYSIS, 48(5). p. 989-996 | Abstract: | A precursor of Y-Ba-Cu oxides was prepared by a modified alkoxide sol-gel method and its thermal decomposition in air was studied by on-line coupled TG-FTIR and High Resolution Thermogravimetric measurements. A continuous more or less stepwise weight loss was observed between room temperature and 600 degrees C at which all organic compounds had evolved and were progressively oxidized as the temperature increased leaving only Y and Cu oxides and bariumcarbonate. Between 700 and 800 degrees C a final weight loss was observed due to the decomposition of bariumcarbonate into oxide. | Notes: | LIMBURGS UNIV CTR,LAB INORGAN & PHYS CHEM,B-3590 DIEPENBEEK,BELGIUM. | Keywords: | sol-gel; TG; thermal decomposition; Y-Ba-Cu superconductors | Document URI: | http://hdl.handle.net/1942/3329 | ISI #: | A1997XH14700006 | Type: | Journal Contribution |
