23_42i/2011Nanoengineered Superconducting Wire: Tailored Materials for High-Performance MgB2 Wire (Adv. Mater. 42/2011)

Low-cost high-performance superconducting MgB2 wires are demonstrated using tailored starting materials.46 As reported on page 4942 by Jung Ho Kim, Sangjun Oh, and co-workers, nanoengi-neered carbon-encapsulated boron powder allows for low sintering temperature and prevents surface oxidation. Furthermore, grain alignment by elon-gated magnesium coarse powder enhances the critical current density up to the level of commercial applications.
