Superconductive junctions between superconductive melt-textured YBa 2Cu 3O 7− δ blocks (MT-YBCO), that are practically invisible in a polarized light, have been made using a TmBa 2Cu 3O 7− δ powder, which is close to materials being joint in superconductive and mechanical properties (microhardness and bending strength). By SEM study we have found that in the best seams Tm has been present in a thin (about 40–50 μm) layer along the seam.
