Abstract
Large-volume HTS tiles with low-angle grain boundaries are obtained by cutt ing melt textured YBa2Cu3O7-x (YBCO) samples parallel to their c-direction and rejoining them with ErBa2Cu3Ox, applying a pressure of 0.5 MPa. This jo ining technique enables the preparation of large monoliths as well as of mo noliths with complex shape which are required for technical application. Sa mples prepared by this technique exhibit high intergranular critical curren t densities up to 10(9) A/m(2) at 55 K and good mechanical connectivity.
