AbstractSuperconducting Y‐Ba‐Cu‐0 film can be prepared by a liquid phase growth method without crucible on 96 % and 99 % alumina substrates. A buffer layer of sputtered gold or platinum was necessary for the formation of Yba2Cu3Ox phase. The flux of Ba2Cu3O10. was appropriate for this purpose. For a film of 10 mm x 20 mm x 10 micron, 0.6 to 0.8 gm initial weight was optimal, the optimum melting temperature was 1090 to 1110 °C for 20 ‐ 30 minutes. In order to obtain films with superconducting transition, an additional Y2BaCuO5‐underlayer was necessary. The resultant optimal films had Tc‐onset of above 80 % and Tc ‐zero of typically around 60 K.
