“…The bulk samples prepared from PAVEZYUM Boron powder (B1 and B3) as precursor powder have larger grains than the commercial Boron powder (B2). The set of samples prepared with Mg1 (325 mesh) powder (11,12,13) and Mg2 (20-230 mesh) powder (21,22,23) shows the same tendency on FWHM values and Mg2 powder set samples have larger FWHM values than the counterpart samples in Mg1 set. Therefore, Mg2 set has a smaller grain size than the Mg1 set.…”

“…After nearly 20 years of research, the effect of MgO on the properties of MgB 2 remains still not fully understood. Some physicists consider MgO to be the main barrier for supercurrent flow, lowering its J c [83][84][85], some researchers believe that MgO is a type of dopant that can boost pinning force and J c in high magnetic fields. Jiang et al, for example, found that adding nanosized MgO to MgB 2 increased J c [86].…”

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.

“…The effect of MgO on MgB 2 , especially in terms of its superconductivity, remains unclear after nearly 20 years of research. Some groups insist that MgO is one of the main barriers of the supercurrent flow, which decreases its critical current density (J c ) [6][7][8]. Some groups believe that MgO is a kind of dopant that can increase the pinning force and J c at the high magnetic field.…”

In this study, boron powder with different particle sizes was purified by both chemical and heat treatment methods. The reduction in the particle size can improve the chemical purification with no effort on the heat treatment. The superconducting properties of the powder drastically changed even with only a partial elimination of oxygen. On the one hand, less oxygen content resulted in high Tc and Jc values under the low magnetic field, and most importantly, a significant improvement in the superconducting connectivity (Af value). On the other hand, the degradation of Jc under a high field and a change in the pinning mechanism were also found, along with decreasing oxygen. This result indicated that oxygen, probably MgO, might act as the pinning center and as an obstacle for the supercurrent in MgB2 at the same time. This work paves the way for obtaining pure oxygen-free MgB2 and understanding the real effect of oxygen in MgB2.
