摘要：

A new fabrication process was used to produce the Y1Ba2Cu4O8 superconductor in a filament form at one atmosphere oxygen pressure. The filament was prepared by dry-spinning with a starting homogeneous aqueous solution containing acetates of a stoichiometric composition of Y:Ba:Cu = 1:2:4, polyvinyl alcohol, propionic acid and 2-hydroxy isobutyric acid. After removing volatile components, the filament heated at 790°C was of the 124 phase, and a mixed structure of the 123 phase and CuO was observed for the filaments heated at 810°C. The filament with the 124 phase exhibited superconductivity at a Tc of 73 K and the filament of the mixed structure of the 123 phase and CuO showed Tc = 84 K. © 1990.
