The preparation of thick films of YBa2Cu3O7-x by diffusion between Y2BaCuO5 substrates and a surface layer of a barium cuprate mixture (BaCuO2, CuO) was investigated. The influence of the substrate microstructure and density on the morphology and properties of the diffusion layer were determined by scanning microscopy and transport current measurements.
