Synthesis, structural and electrical properties of double perovskite Sr <inf>2</inf>NiMoO <inf>6</inf> ceramics

The double perovskite Sr 2NiMoO 6 powders and ceramics were prepared by two different (conventional and precursor) solid-state reaction methods. The phase structure was characterized by XRD and TEM techniques. It has been indicated that single-phase perovskite powders were obtained when calcined in...
