Abstract
We report here the successful synthesis of the superconductor YBa2Cu4O8(1-2-4) through a solution based "sol-gel" technique which vastly simplifies its preparation. Unlike the conventional route, this does not require a high oxygen pressure during synthesis and yields totally single phase material. The technique involves formation in solution, of a fine-particle complex based precursor. The 1-2-4 phase, with a Tc of 80K, is found to form in flowing oxygen with a single firing of 30 minutes at 900°C.
