We present our research on the influence of pressure on the synthesis of the MgB 2 phase
and, consequently, on the superconducting properties of the MgB 2 system. We investigated …

The doping effect of Ti and Zr on the superconducting properties and the microstructure of
sintered MgB2 bulk materials has been studied. The transition metal is found to work as a …

We report on the results of a comparative investigation of highly dense bulk MgB 2 samples
prepared by three methods:(i) hot deformation;(ii) high pressure sintering; and (iii) …

The present investigation focuses on methods to further improve the J c values of disk-
shaped bulk MgB 2 superconductors by optimizing the sintering conditions. We prepared …

The addition of Ta (2–10 wt.%) to a starting mixture of Mg and B (taken in the MgB2
stoichiometry) and application of high pressure (2 GPa) during the synthesis process (800 …

We present the superconducting properties and phase compositions of Mg 1− x Zr x B 2 bulk
samples fabricated by a solid-state reaction at ambient pressure. It is found that a small …

The MgB 2 superconductor bulks were prepared by hot-pressing under the pressure of 55
MPa at different temperatures of 650∘ C, 700∘ C, 800∘ C, 900∘ C, 1000∘ C, respectively …

Pure MgB 2 bulk samples were sintered in different atmospheres: high purity Ar, high purity
Ar with 0.01% O 2, high purity Ar with 0.03% O 2 and high purity Ar with 5% H 2. The …

MgB 2 bulks with excess Mg addition were rapidly synthesized by sintering at low
temperature in present work. It is found that even after ball milling treatment of original …

In previous studies, we found that bulk MgB 2 contained numerous voids in various shapes
and sizes. With the aim of improving the critical current density as well as the mechanical …
