Abstract
We report the successful synthesis in air of the superconductor YBa2Cu4O8 (1-2-4) without the need of high oxygen pressure or an alkali-carbonate based catalyst. The technique involves formation, in solution, of a fine-particle-complex based precursor. The 1-2-4 phase then forms in air with a single firing of 30 min at 900°C and a Tc near 80 K. We also report some results of attempts to prepare 1-2-4 using precursors from sol-gel and spray drying.
