This review paper summarizes and analyses the current literature on the synthesis of dense
MgB 2 bulk with high density and by both the modified solid reaction method and the Mg …

In this review, we present a new set of machine learning-based materials research
methodologies for polycrystalline materials developed through the Core Research for …

A trapped field of over 3 T has been measured at 17.5 K in a magnetized stack of two disc-
shaped bulk MgB 2 superconductors of diameter 25 mm and thickness 5.4 mm. The bulk …

In this study, high-density magnesium diboride (MgB2) bulk superconductors were
synthesized by spark plasma sintering (SPS) under pressure to improve the field …

Nanocrystalline MgB 2 bulk superconductors have been fabricated by ultra-high pressure-
assisted sintering (∼ 5 GPa) over a range of temperatures (700° C-1100° C). Phase …

Spark Plasma Sintering is a promising rapid consolidation technique that allows a better
understanding and manipulating of sintering kinetics and therefore makes it possible to …

The transport current carrying capacity of ex situ processed MgB 2 is expected to be greatly
enhanced if a strong intergrain connectivity can be realized. Although percolation theory …

Superconducting bulks of MgB2 were obtained by an ex-situ two-temperature route applied
to spark plasma sintering (SPS). Processing of samples was performed at lower …

This work investigates a new processing method developed to improve the connectivity of ex-
situ MgB 2 bulks at low sintering temperatures. Mg additions (1–10 wt.%) were mixed to pre …

The two most common types of MgB 2 conductor fabrication technique–in-situ and ex-situ–
show increasing conflicts concerning the connectivity, an effective current-carrying cross …
