Abstract

A purifying process was used to remove the B₂O₃ from the oxidized B powder. The samples made with purified B powder show higher J_c. The improvement of the Jc was attributed to the remove of the B₂O₃ from the B powder, and correspondingly, causing less MgO in the MgB₂ during the later sintering.
