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

ABSTRAKT

Ammonium dinitramide, or ADN (NH4N(NO2)2), is a new and promising oxidizer with high impulse and high burning rate. It is a potential replacement for ammonium perchlorate (NH4ClO4 or AP). Since ADN does not contain chlorine, a composite rocket propellant containing ADN and a polymer binder will produce minimal smoke, and will be more environmentally friendly compared to propellants based on AP. There are, however, some drawbacks: ADN is relatively shock sensitive, it is also sensitive to light and moisture. Moreover, ADN has until now been very expensive to produce. This paper presents a study of the sensitivity, thermal stability, and some spectroscopic properties of ADN. The paper also presents a comparison of the impulse of composite propellants based on ADN and oxidizers such as AN, AP, CL-20 and HNF, with HTPB as a binder. The ADN used in this work was synthesized at the National Defence Research Establishment (FOA), by a new and much less expensive method. The friction sensitivity of ADN is much lower than that of RDX. The impact sensitivity of ADN is of the same magnitude as that of RDX but varies a great deal with the shape of the particles, e.g. prilled ADN is nearly twice as insensitive as RDX. The reaction of ADN is also less violent. The ignition temperature was determined to be 160°C (by Wood's metal bath). The thermal stability, measured with microcalorimetry, shows that ADN is stable to at least 80°C and that impurities cause decreased thermal stability. The activation energy (Ea = 158 kJ/mole) and frequency factor (K0 = 6.0·1015 s−1) was determined from DSC data using the ASTM method E 698-79. It was also found that ADN in aqueous solution is sensitive to light.
