Abstract

MgB2 is a kind of newly-developed superconductor which can be potentially applied in many fields such as MRI, wind turbine generator and fault current limiter. The performance of a MgB2 superconductor is substantially influenced by the microstructure and properties such as porosity, connectivity, grain size and upper critical fields.

This talk briefly presents the current status of MgB2 superconducting wire research. It focuses on the so-called "advanced internal Mg infiltration, AIMI" route, which has been developed by our group and resulted in a performance improvement by 3-10 times. Also this presentation introduces some recent attempts such as oxygen doping and texturing for the purpose of product improvements in the future.
