Systematic research on the improvement in J c of MgB 2 bulks by the optimization of
sintering conditions was performed by applying a highly reproducible fabrication method …

We present a detailed analysis of the effects of excess Mg on the lattice parameters, the
critical temperature (T c), the critical current (J c), the irreversibility field (H irr), and the upper …

MgB 2 bulks were synthesized by the solid-state reaction of Mg and B at 600 C and their
superconducting properties were compared with samples heated at 850 C. The samples …

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 …

A systematic study on the superconducting properties of polycrystalline MgB2 synthesized
by in situ Powder-In-Sealed-Tube technique is carried out at different temperatures (750 …

We succeeded in the synthesis of high-Jc MgB2 bulks via high energy ball-milling of
elemental Mg and B powder at ambient temperatures. The mixed powder was ball-milled for …

Doping effects of B/sub 4/C and SiC on the superconducting properties of MgB/sub 2/bulks
synthesized by low-temperature solid-solid reaction and high-temperature liquid-solid …

We prepared bulk MgB2 from high‐purity commercial powders of Mg metal (99.9% purity)
and amorphous B (99% purity) powders using a single‐step solid state reaction at 775° C for …

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) …

An autoxidation treatment of short-time milled original powders was introduced for the
synthesis of MgB 2 superconductors and the critical current density J c of the sintered MgB 2 …
