The texture and structure of polycrystalline films of Bi-Sr-Ca-Cu-O prepared by the paint-on method on alumina substrate has been investigated. A large variety of texture strength has been obtained as a result of various processing of 2:2:1:2, 1:1:1:2, 1:1:2:2 and 2:2:2:3 compounds. The X-ray diffraction analysis and measurements of conductivity have shown the presence of a low Tc phase. Imaging of the magnetic field distribution using the Faraday effect and the critical current measurements demonstrated that the critical current is very low. SEM observation of the microstructure indicate that the possible reason of low critical current density is a weak link between high Tc grains.
