Enhancement in critical current density and irreversibility field of bulk MgB2 by C and CaCO3 co-addition

Enhancement in critical current density and irreversibility field of bulk MgB2 by C and CaCO3 co-addition

Paper ash, a source of C and CaCO3, was used for the first time as a cheap form of sub-micron particles for doping. 0–10 wt% of the ash was added to Mg + 2B and in situ reacted at 850 ◦C for 30 min in flowing Ar atmosphere. The CaCO3 decomposed and reacted with B to form CaB6 as an impurity phase. A...
