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: 0.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.7 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: 0.00016 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: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

RESUMO

This paper reports measurements of the burning velocity of powder mixtures of aluminium and molybdenum trioxide in nitrogen at atmospheric pressure. The burning wave was detected by measuring the electric resistance of two wires laying on the specimen surface, separated by a known distance. Analysis of video recordings of the burn provided an additional measure of the burning velocity. Specimens were prepared by pressing the powder mixture at 296 MPa. The specimens were prism-like with dimensions of 80.4 by 8.15 by approximately 3.5 mm. Stoichiometric mixtures diluted with alumina were prepared, plus one rich, undiluted mixture. Six dilution compositions were tested: 0.0, 9.3, 13.4, 17.1, 23.6 and 30.5 mass percent alumina. The rich mixture had an equivalence ratio of 1.71. Burning velocity of the stoichiometric mixtures decreased almost linearly with dilution, going from 12.8 mm/s for undiluted to 4.2 mm/s for maximum dilution. Burning speed for the rich, undiluted mixture was 36.3 mm/s. The reaction produced a large quantity of gases, which scattered the products of the undiluted mixtures. Analysis of the recovered products showed the existence of aluminates, and besides alumina, molybdenum and molybdenum oxides.
