Transformation of MgB2 powder into superconducting film via electrophoretic deposition technique

Simple, Green, and High‐Yield Production of Boron‐Based Nanostructures with Diverse Morphologies by Dissolution and Recrystallization of Layered Magnesium Diboride Crystals in Water

“…The bands located at <1000 cm −1 agree well with the modes of β‐rhombohedral boron, as shown by Sundar et al., and the A 2u mode of MgB 2 appears at ≈405 cm −1 (see Figure S11 g). The bands at >1000 cm −1 for the filtrate samples at different aging times indicate the presence of the Mg−B, B−B, B−OH, B−O, B−H, B−H−B, and O−H bonds . The presence of hydrides, oxides, and hydroxide functional groups on the standard MgB 2 powder sample is attributed to its hygroscopic nature.…”

“…The bands at ñ > 1000 cm À1 for the filtrate samples at different aging times indicate the presence of the MgÀB, BÀB, BÀOH, BÀO, BÀH, BÀHÀB, and OÀHb onds. [69][70][71][74][75][76][77] The presence of hydrides, oxides, and hydroxide functional groups on the standard MgB 2 powder sample is attributed to its hygroscopic nature.H owever,t hese functional groups are more pronounced in the spectrao ft he filtrate than in the spectrum of the standard MgB 2 powder (see Figure 7b). This observation suggestst hat these functional groups are likely attained due to the chemical reaction between MgB 2 and water,w hich is supported by the GC-MS results (as mentioned above).…”

Electrophoretic deposition of La2Zr2O7 coating in non-aqueous media on Cf/SiC substrate

“…M.B. Kadam et al [13] showed that triiodide ion formation is often observed in many donor-iodine acceptor systems when the medium is highly polar. The rapid reaction of ethanol with iodine initially occurs, and then the outer complex is formed.…”

Synthesis of MgB2 superconductor under carbon induced virtual inert atmosphere

“…So there is a need to develop economical and least complicated technique which will synthesize comparatively dense carbon doped MgB 2 samples at ambient atmosphere. In this line, the authors have already worked out the low cost synthesis of MgB 2 thin film by electrodeposition [19,20], electrocrystallization [21][22][23] and electrophoretic techniques [24,25]. The present preparation techniques used for the synthesis of MgB 2 superconductors involves hot pressing [26,27] or hot isostatic pressing, ball milling [28], hot deformation [17], high pressure sintering, mechanical alloying [29], self-propagating high temperature synthesis [30], powder in sealed tube method [31], co-evaporation method [32], etc.…”
