Textured bulk YBa2Cu3Ox superconductor samples were fabricated using directional growth of superconductor grains reacted from Y2BaCuO5, BaCuO2, and CuO powder mixtures. The samples consisted of several mm long grains aligned parallel to the growth direction. The microstructure observation and x-ray diffraction analysis showed that the grains have a preferred orientation to improve critical current density.
