Phase Transitions in Bi/Ca Modified AgNbO3 Ceramics with Excellent Energy Storage Density and Storage Intensity

Small, Volume 21, Issue 32, August 14, 2025.
The debated ±EU current peaks are readily distinguished from the ±E2 current peaks in modified AgNbO3 ceramics, which show a particularly high recoverable energy density of 4.4 J cm⁻3 and a superhigh energy storage intensity of 21.46 × 10⁻3 J kV⁻¹ cm⁻2 at a low field of 205 kV cm⁻¹.

Structure, Dielectric, and Electrical Characterization of 0.9(Bi0.5Na0.5TiO3) – 0.1(Bi0.5Sr0.25TiO3) (BNT-BST) Solid Solution for Capacitor Applications

Journal of Advanced College of Engineering and Management
Eco-friendly 0.9(Bi0.5Na0.5TiO3) - 0.1(Bi0.5Sr0.25TiO3) (BNT-BST) ceramics were synthesized via the solid-state reaction method. Structural, dielectric, and electrical properties were systematically studied. Rietveld refinement confirmed a pure rhombohedral perovskite structure with R3c symmetry. The dielectric constant peaked at 3456 @1kHz with a high

Physical Properties of the K0.5Na0.5NbO3 Compound Doped With Li, La, and Ti in Concentration Lower Than 1.3 mol%

International Journal of Ceramic Engineering &Science, Volume 7, Issue 4, July 2025.
Doping of KNN with Li, La, and Ti at concentrations less than 1.3 mol%, reduces structural defects, increases density, and enlarges grain size. These changes enhance the remnant polarization and pyroelectric response. Thermal diffusivity decreases when doping's leads to higher concentrations of the secondary phase.
