Realizing Ultrahigh Dielectric Constant With Ultrawide Temperature Stability in Dual‐Phase BNT‐BST Ceramics by SPS Sintering

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Ceramic capacitors are critical components in advanced electronic devices, primarily due to their multi‐functionalities in energy/information storage and conversion. However, poor temperature stability remains a long‐standing challenge for practical applications, especially at extremely high‐ or low‐temperature conditions (e.g., > 200°C or ...

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

open access: yesInternational 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.
