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

ABSTRAKT

The residence time of the particles in reactive thermal plasma governs mechanisms occuring at high temperature, (solid ® liquid, liquid ® vapor and oxydation Si1 + Og ® SiOg). The goal is to control the process of particles purification with a partial evaporation in order to have a good yield of manufacture of ultra-pure silicon, hi mis study, it is evaluated from L.D.A. measurements, which provide the particle velocity. Experimental measurements by optical Emission Spectroscopy (O.E.S.), confirm the gas temperature range surrounding the particle, down stream all along the 30 cm trajectories. The most remarkable result of particle velocity obtained from L.D.A. measurements on one hand, and particle velocity obtained from modeling calculation and ab-initio numerical calculation on the other hand are in a good fitting, which confirm particles residence time t Part. along 30 cm trajectory.
