“…High-purity commercial Mg metal powder and two types of crystalline boron, namely encapsulated-coated boron and amorphous boron powders with nanometre-sized particles were individually combined in the stoichiometric ratio to prepare bulk MgB 2 [63]. It was found that combining carboncoated nano boron with crystalline boron increases bulk MgB 2 performance.…”

Although the fascinating effect of superconductivity was discovered more than one hundred years ago, only a few low-temperature superconductors, especially Nb3Sn and NbTi, have reached everyday-life use. After the discovery of superconductivity in MgB2 in 2001, a boom appeared in interest in employing MgB2 in commercial applications, facilitated by simple crystallographic structure, high critical temperature, low-cost raw ingredients, simple and fast production, and other advantages for moderate temperature applications. It only lacks high flux pinning and good mechanical performance. In this review, the implications of manufacturing procedures on the superconducting properties, crystal and electronic structure of MgB2 are discussed. The advantages and drawbacks of various manufacturing processes will be presented, as well as the ways how to improve MgB2 superconducting performance. The impact of oxygen reduction, elements doping, the introduction of defects and additives, and the effect of precursor refinement on superconducting properties are here compiled to give an overview of the progress of flux pinning enhancement in bulk MgB2.
