MgB2 Superconductor Project

Preparing Samples

1) Weigh appropriate amounts of Mg and B powders.
2) Mix and grind powders (in mortar) for ~ 15 minutes.
3) Pack and press the resulting powder into sheathing material.
4) Mechanically deform sample (crush the core) into a slug, ribbon or wire.
5) Heat (possibly two or more temps for two or more times).

Processing Post-Reacted Samples

1) Possibly mechanically deform again. 2) Possibly sinter again. 2) Cut off sample ends (exposing clean sample cores).
3) Polish sample ends.
