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

RESUMO

Inductively coupled plasma was studied to assess the feasibility of plasma flash evaporation of high-melting materials. The evaporation time of zirconia particles in thermal plasma of 10,000 K was estimated to be 90 and 560 µs for spherical particles with radii of 5 and 12.5 µm, respectively. Inductively coupled argon-hydrogen plasma was generated with a power of 30 kW at a frequency of 4 MHz. Its temperature as inferred from intensity ratios of spectral lines of singly ionized Zr amounted to between 7000 and 8600 K, depending on pressure, thus allowing for the existence of zirconia vapor. It was shown that by laser light scattering zirconia particles with a maximum diameter of 12 µm could be vaporized at a rate of at least 200 mg/min, if the hydrogen fraction of the argon-hydrogen plasma was sufficiently high.
