Summary

The critical current density and trapped field of large grain RE123 bulk superconductors have drastically increased in the last few years. High-quality bulk superconducting magnets can trap a very high magnetic field of 3 T at 77 K and above 15 T at 20 K. The recent progress in bulk superconducting materials has led to many applications such as superconducting flywheel systems, current leads, superconducting motors and magnetic separation systems and magnetron sputtering machines. In the paper, the authors review recent research and development on the processing, critical current density, trapped field and mechanical properties of melt-textured bulk superconducting materials.
