Abstract

Screen printing was employed to fabricate thick films of the composition (Tl0.6 Bi0.16 Pb0.24 )(Ba0.1 Sr0.9 )2 Ca2 Cu3 Oy on polycrystalline Y2 O3 -doped ZrO2 substrates. The influence of the screen printing procedure, the heat-treatment of the films and additional compaction on the texturing of the superconducting crystallites and on the electrical properties of the superconducting films have been studied. X-ray diffraction ascertained the high phase purity of the material and allowed calculation of the degree of texturing. Scanning electron microscopy in combination with EDX and optical microscopy in normal and polarized light yielded information about the microstructure of the films. T c (0) values of 118 K and transport critical current densities in the range of 10 kA cm-2 at 77 K were obtained for the best specimens.
