Abstract
Films of BiSrCaCuO with metal ratios 4:3:3:6 of thickness 20 mu m have been produced by two paint-on methods. The first involved applying a suspension of the metal oxides and carbonates to a sapphire substrate and sintering. The second used pre-reacted superconducting BiSrCaCuO powder suspended in an organic medium and applied to a substrate. The films have shown superconducting transitions with onset at 80K and zero resistance at 73K. The effects of the bake cycle are discussed with reference to T sub c and room-temperature resistance, and the two methods are compared. 9 ref.--AA
