The top seeded infiltration and growth process (TSIG) is an effective way for the preparation of bulk REBa2Cu3O7−x (RE-123) with finely dispersed RE2BaCuO5 (RE-211) particles compared to the conventional melt growth (MG) method. However, it is more complicated and time-consuming because three kinds of precursor powders, involving RE-211, RE-123, and BaCuO2, have to be prepared before the conventional TSIG process. In this article, a new liquid source (NLS) composed of RE2O3 (RE-200), BaCuO2, and CuO powders, has been found for simplifying the TSIG process, which is different from the regular liquid source (RLS) composed of RE-123 and Ba3Cu5O8. In this modified TSIG technique, what we need is only to prepare RE-211 and BaCuO2 precursor powders for the whole TSIG flow. Single-domain GdBCO bulk superconductors have been fabricated using the RLS and NLS separately. The morphology, microstructure, and levitation force of the GdBCO bulks have also been investigated. The results indicate that the NLS can be used to simplify the process flow, reduce the cost and improve the efficiency on the fabrication of single-domain GdBCO superconductors.
