The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

要約

Smelting of Nb2O5 was carried out in a dc extended arc argon plasma using carbon as the reductant. Plasma was produced in a reactor operating in transferred arc configuration (normal polarity mode). The plasma smelted product was analysed and found to contain up to 97.5% Nb with 86% (all by wt.) metal recovery. Characterization of the smelted product by XRD shows that majority of reflections are due to Nb metal and carbon occurs in the form of carbide. One minor reflection due to Nb2O5 was recorded which is attributed to the unreacted oxide. Wavelength dispersive spectra of x-ray confirmed the carbon presence in the smelted product. Micro Raman spectroscopy study makes a comparison between the spectra due to smelted product and that of high pure superconductor grade Nb in order to identify presence of any carbide and/or oxide in the metal. Optical and scanning electron microscope studies reveal the typical surface morphologies of the plasma smelted Nb. Plasma smelted Nb has a good scope for use as a starting material towards preparation of high pure Nb for application in superconductors and electronic capacitors . This can be achieved by suitable removal of carbon followed by electron beam melting of themetal.
