High energy ball milling is used for the purpose of studying particle-size reduction/nanometer-scale grain-size refinement relationship to critical properties (current and magnetic field) enhancements.

Characterization techniques include: High Resolution Transmission Electron Microscopy (HRTEM), Scanning and Tunneling Scanning Electron Microscopy and, X-ray Diffraction

Ball Milling techniques in processing both pre-cast and powder blends (via mechanical alloying) to enhance the flux pinning in MgB2.

We are looking for the optimum condition to maintain the good connectivity between grains.

Further research is currently being carried out with the collaboration of the Wisconsin group headed by Professor Eric Hellstrom (UW-Madison). Glove box from Wisconsin is here at UPRM.
