Etude physico-chimique de deux molybdo-arséniates NaAg2Mo3AsO13 et Na2AgMo3AsO13 Corrélations structures-propriétés électriques

Written by sctunisie no comments

Structural study of NaAg2Mo3AsO13 and Na2AgMo3AsO13 compounds confirms that they were build by one dimensional framework formed by ribbons running along [100] direction. Ag+ and Na+ ions are located in the inter ribbons space. Those phases were characterized by powder and single–crystal X-ray analysis, scanning electronic microscopy (S.E.M.) and infrared spectroscopy (I.R.). The conductivity study was realized by complex impedance spectrometry (I.C.S.) and the differential scanning calorimetric analysis (D.S.C.).
