Although the fascinating effect of superconductivity was discovered more than 100 years
ago, only a few low-temperature superconductors, especially Nb 3 Sn and NbTi, have …

In this work, ex situ MgB2 bulks were added with (1.5 Mg+ 2B) and sintered in an attempt to
enhance its intergrain connectivity. The addition was varied within the range of 0–50 wt …

Recently, novel low cost techniques have been employed to improve critical current density
of MgB 2. Ultra-sonication is one such technique. We report on the influence of hexane …

Cheap commercial boron was refined ultra-sonically in distilled water medium for various
durations. X-ray diffraction pattern (XRD) indicated impurity-free nature of ultra-sonically …

High-density MgB 2 bulks with superior mechanical and superconducting properties were
fabricated using spark plasma sintering (SPS). The sharp superconducting transition at 37.5 …

Viscosity of solvent has been found to influence particle refinement during high-energy ultra-
sonic treatment. 2-propanol, a solvent with viscosity∼ 2.07 cP, was used to ultra-sonically …

We studied the effect of carbon (C) ion implantation on the microstructure and
superconducting properties of bulk MgB 2 prepared by the powder-in-sealed-tube (PIST) …

Nanocrystalline superconducting MgB 2 bulks were prepared by high pressure sintering of
ball milled MgB 2 powders. The disorder produced in these nanocrystalline materials shows …

MgB2/Fe superconducting wires were synthesized by sintering at 850° C for 2 h using low
purity B source by using the Localized Internal Mg Diffusion (LIMD) technique, a type of …

The synthesis of bulk MgB 2 superconductors from Mg and MgB 4 precursors instead of the
conventional in situ process increases the packing density, but further enhancement of the …
