Superior dielectric temperature stability and high energy-storage density of ecologically friendly 0.7(0.94Bi0.5Na0.5TiO3–0.06BaTiO3)-0.3Ba(Mg1/3Ta2/3)O3 ceramics
Recently, much attention has been given to dielectric ceramic capacitors, which have excellent temperature stability and a high energy-storage density. Ecologically friendly ceramics ((1-x)(0.94Bi0.5Na0.5TiO3–0.06BaTiO3)-xBa(Mg1/3Ta2/3)O3, where x = 0, 0.15, 0.2, 0.25, or 0.3) were synthesised using a conventional solid-state method. The ceramic sample with x = 0.3 exhibited a superior dielectric temperature stability, relative permittivity that varied within ±15%, and low dielectric loss of less than 0.02 over a temperature range of −100 to +307 °C, which met the X9R specifications. In addition, a scanning electron microscopy image confirmed that the sample had a dense and uniform microstructure. Furthermore, a high recoverable energy-storage density of 6.75 J/cm3 was obtained for the ceramic sample with x = 0.3 under a moderate applied electric field of 420 kV/cm. These characteristics suggest that it is a promising candidate for an ecologically friendly temperature-insensitive dielectric ceramic for energy-storage capacitors.
期刊介绍：
Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
