Mechanochemical synthesis and characterisation of bismuth-niobium oxide ion conductors
Bismuth niobate solid solutions, BixNbOδ(2.5≤x≤6), have been prepared using a mechanochemical method. The solid solutions were also prepared using a solid-state conventional method for comparison purposes. Bi3NbO7 was successfully obtained via a mechanochemical method at a lower synthesis temperatur...

| description | Bismuth niobate solid solutions, BixNbOδ(2.5≤x≤6), have been prepared using a mechanochemical method. The solid solutions were also prepared using a solid-state conventional method for comparison purposes. Bi3NbO7 was successfully obtained via a mechanochemical method at a lower synthesis temperature (milled at 1000 rpm for one hour followed by heating at 700oC for 24 h) than the conventional solid-state method. Electrical properties of the single-phase materials were studied by AC impedance
spectroscopy. Further characterization of the materials was carried out using differential thermal analysis (DTA) and thermogravimetric analysis (TGA). The results showed that
no thermal changes and phase transitions were observed and all materials were thermally stable. |
