Making A1 A15s



A15 Intermetallic superconductors do not receive as much media hype as the high-Tc ceramic variety but they are big business, especially in the superconducting magnets area. This rapidly growing research field which includes melt-spinning and rapid solidification technology is surveyed, and a report of the synthesis of Nb3Ge with critical currents of 5 × 1010 and 8 × 1010 A/M2 at fields of 0 and 15 T respectively is reviewed.
