摘要: ABSTRACTIn the research, properties of sodium copper titanate niobate – barium [(1-x)NaCu3Ti3NbO12-(x)BaTiO3: (1-x)NCTNO-(x)BT] ceramics prepared by conventional solid-state reaction method with various molecular weight BT or x between 0.1, 0.3 and 0.5 were investigated. These sintered at 975, 1000, 1025 1050 oC for 10 h in ambient atmosphere. The phase structure, microstructure, density, micro-hardness dielectric examined x-ray diffraction technique (XRD), scanning electron microscopy (SEM), Archimedes method, Vickers tester impedance analyzer, respectively. It was found that, addition BaTiO3 resulted formation second which increased upon increasing content. Compared to base composition, grain sizes all (1-x)NCTNO-(x)BT significantly reduced. densities improved BaTiO3. For effect sinter...
