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

RÉSUMÉ

The reactivity of each lanthanum and manganese nitrate and chloride is studied in four molten media, NaN03, NaN02, KN03 and KNO2 at 500 °C. The lanthanum salts produce mainly hydroxide and oxychloride. The manganese salts give a variety of compounds, mainly oxides and also oxychloride and sodium manganate. The reaction of the mixed metal salts leads to the perovskite non-stoichiometric La1-xMnO3. The results can be interpreted in terms of acido-basicity of the lanthanum ion and of oxidation pathway of the manganese species. The simultaneous presence of both metal ions in the media forces La1-xMn03 to precipitate. The obtained crystallites are nanosized with a large surface area.
