During sintering, liquid Mg-Ni phase prompts solid-solid reaction between Mg and B and the size of milled Ni powder determines the final distribution of the secondary MgNi2.5B2 phase in the sintered samples. A flux jump was observed in the (MgB2)0.96Ni0.04 samples doping with Ni powders. Recognized from the measured superconductive properties, smaller-sized Ni powders can provide more effective flux pinning centers and thus improve the performance of the critical current density.
